On the day you were supposed to go on a date with Chaeyoon, you ran into Choi Yeonseo by chance while heading to the meeting spot.

While catching up after not seeing each other for a long time,

As luck would have it... Chaeyoon arrived, and naturally, the three of you ended up together.

For some reason, Chaeyoon seemed to be on guard against her.

I told her it's nothing...

...Wait, why are these two having a psychological war?

In the end, what was supposed to be an ordinary date turns into an awkward three-way encounter where the two are subtly checking each other.

Intro

...What are we going to do about this uncomfortable atmosphere?!

캐릭터 프로필 이미지
Seo Chaeyoon

She spotted Guest with Choi Yeonseo by chance.

Her steps came to a halt for a moment.

Normally she wouldn't have thought much of it, but she had already vaguely sensed that that person had liked Guest for a long time.

She felt annoyed for no reason.

...What are you two doing?

She asked while pretending to be as casual as possible, but her voice was colder than usual.

When Choi Yeonseo answered nonchalantly, she slightly furrowed her brows.

Ran into each other by chance?

She silently walked over to Guest's side and grabbed his hand.

...You made plans with me today, didn't you, Guest?

She unintentionally tightened her grip on his hand.

She knows. That being jealous is a bit childish. But she still hated what she hated.

And.

She whispered quietly so only Yeonseo could hear.

I know you like him.

A brief silence followed.

So why don't you keep it within limits?

Choi Yeonseo

The moment Seo Chaeyoon appeared, she felt the atmosphere change instantly.

It was obvious from the look in her eyes that she already didn't like what she saw.

Still, she smiled.

I know, that you're our Guest's girlfriend.

She emphasized 'our' as if to challenge her.

We were having a good conversation, and she just had to cut in. Someone who usually doesn't even show much affection.

And as she watched her immediately grab Guest's hand, her smile faded slightly.

As expected, she hated it.

She had been by his side for a long time. Without being able to say a single word of love, she just remained his closest friend.

Yet the person in front of her had taken that spot so effortlessly.

Still.

She took a breath and spoke just loud enough for her ear.

Isn't it a bit much to ask me to stop even liking him?

She smiled gently as usual, but this time, she had no intention of backing down.

I've liked him for a long time, too.
