A psychological test that reveals your cheating rate

Even if you vow eternal love at your wedding, or someone shouts “You’re the only one for me!” when they confess, people’s feelings naturally change over time.
The saying “You don’t feed the fish once it’s caught” is apt—before you know it, your feelings may shift to someone else, and in the worst case, you might cheat or be cheated on.
This psychology test reveals how prone you are to infidelity.
It’s recommended for those who want to check their own likelihood of cheating, or for anyone in a long-distance relationship who feels their partner’s behavior seems suspicious.
Try using it together over LINE.
Just remember: the results are only a rough guide!
A psychology test that reveals the compatibility you seek in a partner based on cat behaviors

We’d like to introduce a psychology test that reveals the kind of compatibility you seek in a partner based on a cat’s behavior—something cat lovers will enjoy, and even dog people should try.
This test shows what your partner wants from you.
All you have to do is answer how the cat in front of you behaves toward you.
Just from that, you’ll find out what’s being asked of you—kindness, strength, and more.
Once you know this, your relationship will be unbeatable! Try it with your partner on LINE.
A personality test that reveals your complexes

A simple psychology test where you pick the color you least want to wear—something you don’t usually think about when choosing clothes—can gently reveal your inner self and mental habits.
The options are distinctly different in character: refreshing blue, calm green, flashy red, and bright pastels.
The fun part is that your choice can suggest unexpected sides of your personality—like “surprisingly introverted? bold? sensitive?”—that you might not have noticed yourself.
It’s enjoyable to answer on intuition alone, and it’s also great for lively comparisons with friends.

A psychology test with 10 questions to see if you’re suited for marriage

People who have lived alone for a long time often say, “I’m so used to living at my own pace that I might not be cut out for marriage,” but is that really true? Liking children or having a homely personality might serve as rough indicators of whether someone is suited for marriage, but still…
So, why not try a psychological test to see if you’re suited for marriage? You might also be a bit curious whether your current partner is marriage material.
Maybe discussing marriage over LINE would make it easier to talk about casually.
A personality test to find out when your popular phase will come and how to attract it

There’s a handy psychology test that can reveal your “popular phase” without having to consult the fortune-tellers you often see around town.
All you have to do is answer a few simple questions, so there’s no reason not to try it, right? Answer seven questions and add up the points assigned to each answer to find out when your popular phase will come! It even tells you how to attract that popular phase at the same time.
If you’re a student eager for romance, it’s sure to be a hit! Try it with your friends on LINE.
A psychological test to find out what truly scares you

Do you know what you’re truly afraid of? If you have to go on a courage test with friends, simply choosing the place you least want to go will reveal what you’re really scared of! The options are: a graveyard, a tunnel that seems haunted, a dark forest, or an abandoned building.
This identifies not a physical object, but the kind of situation that frightens you.
Even if the result isn’t what you thought, you might actually feel fear deep down.
Try using this as a chance to reflect on yourself.
A personality test that shows recommended ways to handle fights with your partner

When a fight breaks out with your partner, many people struggle with how to resolve it.
This psychological test helps you explore what solution suits you best, recognizing that the ideal approach varies from person to person.
The questions are simple—think about your favorite sport or the sport you often watch—and from that, we can determine your way of thinking and the most effective solution.
Relying on just one person’s opinion can sometimes lead to further conflict, so if you understand each other’s perspectives in advance, you may be able to resolve things more smoothly when the time comes.
