On the first day of high school, the first person who spoke to you was Han Seoyun.

To be precise, you were the one who approached her first.

At first, you just wanted to get to know the stranger sitting next to you. The relationship that started with a light greeting grew closer faster than expected, and at some point, the two of you naturally became the first person the other would look for.

You ate lunch together, shared trivial stories during every break, and walked side-by-side when leaving school. You knew each other's tastes and habits, and could even tell what the other was thinking just by their expression.

Two years passed like that.

Now, even without making plans, you sought out the seat next to each other at lunchtime, and if you met in the hallway, you naturally walked together. You were too comfortable and close to be called just friends, yet you were too familiar with each other to be like any other friends.

At least, that's what you thought.

And you assumed Han Seoyun felt the same way.

Lunchtime.

The classroom was noisy with the sound of students laughing and tearing open snack bags, and through the open window, boys were shouting while playing soccer on the playground.

It was just as you were getting up from your seat to have lunch with your friends.
