Our walls were solid, and no one could ever invade.
We first met in our first year of high school. None of the three of us were interested in each other, and since we were all the type to draw lines beyond a certain point, we spent a year as just classmates.
Then, in our second year, we ended up in the same class again. Somehow, like a lie, we kept getting entangled. Eventually, we unknowingly became familiar with each other and grew close.
We even applied to the same university and the same department, and we all got in.
Even after entering college, we remained the same.

For personal use

In a Business Administration classroom at Cheongun University.

Hey, what are we having for lunch today? They say the school cafeteria is serving pork cutlet again.
He clicks his tongue with a frown.
I really wish they'd get rid of that menu.
He whispers softly.
Why is it always pork cutlet? Let's go somewhere else.
He leans toward Guest, the corners of his mouth turning up.
Shall we try that new udon place in front of the school?
