Does a “Soulmate” Really Exist?
The term “soulmate” has a romantic ring to it, doesn’t it?
Many people dream of a fateful encounter, just like in movies or dramas.
But what about in reality?
Is there really only one person meant for us?
Or does our choice determine who becomes our “destined partner”?
Let’s first explore how this concept came to be and how it influences relationships.

The Concept of “Red Thread” and “Soulmate”
The idea of a “destined partner” is found across cultures worldwide.
In Japan, the “Red Thread of Fate” is a well-known legend.
It is said that people are invisibly connected by a red thread from birth, ensuring they will meet no matter how far apart they are.
This concept originates from the Chinese legend of the “Old Man Under the Moon,” who ties lovers together with an invisible string.
In the West, a similar idea exists in the form of “soulmates.”
According to the ancient Greek philosopher Plato, humans were originally one being, made of both male and female parts.
But they were split apart by the gods, forcing them to search for their other half.
It’s a touching and romantic story, isn’t it?
- The concept of “destined partners” exists in many cultures
- Japan and China focus on “threads of fate,” while Western beliefs emphasize “soul connections”
- These ideas can heighten romantic expectations but also influence real relationships

The Psychological Impact of Believing in a “Soulmate”
When we hear “soulmate,” it’s easy to think, “This person is the one!”
However, psychology suggests that this belief can significantly influence our approach to relationships.
Studies indicate that people generally fall into two categories regarding how they view love:
Destiny Belief and Growth Belief.
Those with a Destiny Belief assume that “there is only one perfect match for me in this world.”
As a result, if they experience disagreements or difficulties with their partner, they might quickly think, “This person isn’t my soulmate after all,” and end the relationship more easily.
On the other hand, those with a Growth Belief see love as something that requires effort and nurturing.
They work through differences, improve communication, and strive to deepen their bond.
This mindset makes them more likely to overcome challenges rather than giving up at the first sign of trouble.
- People with a “Destiny Belief” tend to end relationships quickly over minor conflicts
- Those with a “Growth Belief” focus on developing their relationship over time
- Belief in “soulmates” can influence relationship longevity and break-up decisions

A Scientific Perspective on “Soulmates”
Does the idea of a “soulmate” truly exist?
While it may sound romantic, from a scientific perspective, love is significantly influenced by hormones and genetics.
By exploring the chemistry in our brains and biological research, we may gain a deeper understanding of our perception of love.

How Love Hormones Shape Our Feelings
When we fall in love, various hormones are released in our brains.
Dopamine, oxytocin, and serotonin each play different roles in shaping our romantic emotions.
- Dopamine
A hormone responsible for excitement and happiness in love.
It contributes to the intense feelings of infatuation that make someone feel like “the one.” - Oxytocin
Released through physical affection and emotional bonding.
Essential for building long-term connections. - Serotonin
Stabilizes emotions and creates a sense of security in a relationship.
Important for maintaining a healthy and balanced love life.
These hormones are not purely dictated by fate but are influenced by experiences and environmental factors.
In other words, feeling that someone is your “soulmate” may be scientifically explained by hormonal responses.

Is Compatibility Determined by Genetics? Biological Research Findings
Recent studies suggest that genetic compatibility may influence romantic attraction.
In particular, the diversity of immune system-related genes (HLA genes) is believed to play a role in attraction.
- HLA Gene Diversity
People tend to be attracted to partners with different HLA genes, which may contribute to healthier offspring from an evolutionary standpoint. - The Connection Between Pheromones and Genetics
People may unconsciously assess genetic compatibility through scent, which helps determine attraction.
However, these studies only suggest tendencies and do not fully explain romantic attraction.
Compatibility is influenced not only by genetic factors but also by shared values, experiences, and communication.

What Are the Chances of Meeting Your Soulmate?
How likely is it to meet your destined partner?
Is there a scientific basis for that moment when you feel, “This person is the one”?
Let’s explore the mathematical probability of finding an ideal partner and practical ways to increase your chances of meeting them.

The Mathematical Probability of Finding an “Ideal Partner”
Finding the “ideal partner” in love may seem purely left to chance.
However, when analyzed from a mathematical perspective, some interesting patterns emerge.
- The Secretary Problem
- Also known as the “Optimal Stopping Theory,” this mathematical strategy helps in making the best choice within limited options.
- For example, if you expect to meet 100 potential partners in your lifetime, the theory suggests observing the first 37 without committing, then choosing the next person who surpasses all previous candidates. This maximizes the probability of finding the best match.
- Probability Theory and Relationship Success
- Based on statistical models, about 10 to 20 people in a lifetime may feel like a “destined” match.
- In other words, broadening your social interactions and meeting more people increases the likelihood of finding the right one.
By applying mathematical theories to love, we gain a fresh perspective on finding a partner.

Practical Ways to Increase Your Chances of Meeting Someone
As mathematical theories suggest, increasing the chances of meeting a soulmate requires actively putting yourself in social situations.
So, what are the best ways to increase your encounters with potential partners?
- Join New Communities
- Participating in hobby groups, classes, or volunteer work allows you to meet new people naturally while engaging in activities you enjoy.
- Leverage Online Platforms
- Using dating apps or social media can be an efficient way to find like-minded individuals.
- However, don’t rely solely on profiles—meeting in person is crucial to truly understand compatibility.
- Embrace Serendipity
- Avoid over-planning and leave room for spontaneity—stop by a new café, strike up conversations while traveling, and welcome unexpected encounters.

Regardless of the method, the key is not to passively wait for fate but to take action yourself.
Love flourishes when you actively create opportunities for connection.

How Should We Perceive a “Soulmate”?
The idea of a “soulmate” sounds romantic, but in reality, love is not a matter of fate—it is built through mutual choices and effort.
Psychologically, long-lasting couples do not think, “Things work because it’s them,” but rather, “We make it work by nurturing our relationship.”
So, how can we build a meaningful relationship without being overly fixated on the idea of a “soulmate”?

Why Love is Determined by “Choice” Rather Than “Fate”
In love, the key is not just the “encounter” but the “choices made after meeting.”
Whether a couple is compatible or not changes over time as they grow together.
Rather than relying on fate, it is mutual effort that truly shapes a relationship.
- The Importance of Communication
Understanding your partner’s feelings and expressing your own effectively deepens the connection - Supporting Each Other’s Growth
Encouraging your partner’s personal growth while continuously evolving yourself helps maintain a strong bond - Aligning Values
Whether someone feels like a “soulmate” depends on the effort to align values and expectations
Building a long-lasting relationship is all about the choices we make every day.

How to Find the Best Partner for Yourself
Rather than searching for a “soulmate,” it is more important to choose a relationship that brings happiness.
Instead of seeking a perfect partner, focusing on building a relationship where both can grow together is the key to long-term love.
- Understanding Yourself
The first step is recognizing your own values and what you truly cherish in a relationship - Clarifying What You Want in a Partner
Instead of focusing on appearance or status, prioritize shared values and fulfilling time spent together - Having a Flexible Mindset
Avoid rigid expectations and stay open to enjoying new aspects of your partner’s personality
Letting go of the idea of a “soulmate” and focusing on building the best relationship for both partners is the true shortcut to a happy love life.

Summary
A “soulmate” is not just a fantasy but something built through choices and effort.
From a scientific perspective, love is influenced by hormones and genetics, but it deepens through shared experiences and actions.
The key is not to decide that someone is “the one,” but to cultivate the best relationship for both partners.
- Love is a series of choices
Relationships are shaped by effort, not fate - Compatibility evolves over time
It’s not just about initial chemistry; relationships grow and change - Focus on a relationship that makes you happy rather than finding ‘the one’
Instead of searching for perfection, find someone you can grow with
