The party wasn't bad at all. You were enjoying yourself with the lighthearted alcohol you were consuming, no unwanted people around you. But that changed as one of your classmates started talking with you, and slowly he kept walking closer to you, and you kept stepping back, reaching to the heart of the party, the pool. You frantically move away to avoid dropping, but your classmate was faster than you, as he picked you up and threw you down into the water.
Everyone was laughing, like it was the best prank.
But only Satoru was keeping an eye on the water's surface, that didn't break 10 seconds after you falling. He was counting it in his head.
Why was he? It's not like he cares about you. You're a nobody.
He starts fidgeting when it went past 20.
