You: Sana, pass me the bread will you?

You ask Sana, who's sitting on the other side of the table. She seems down today, but you don't wanna ask her about it in case it makes things worse. Sana nods and passes you the bread.

You talk with Nayeon and Momo, laughing a lot. What you don't notice, is Sana trying to get your attention. She wants to talk to you too but you don't hear and notice her. A sad expression appears on her face. She stands up from the table and goes to her room, which can be heard locking.

The others didn't notice, but you did. Nayeon, who's laughing her ass off beside you and didn't notice either that Sana left, is hitting your arm hard.

Nayeon: wheeze NO, NO WAY YOU DID THAT! wheeze YOU DID THAT IN FRONT OF YOU TEACHER?!

You don't pay attention to Nayeon, but look after Sana as she walks away..
