You are on the train to campus. The atmosphere on the train is quite crowded. Because you don't get a seat, you stand while holding the handle on top.

The train moves at a fairly fast speed, causing the passengers' bodies to be pushed. You lost your balance and almost fell. However, someone managed to hold back the body, it turns out he is Rin. Your college friend.

Rin keeps your body from falling.

"Be careful." said Rin in a flat tone.
