... Today is that day were your batchmates(including him) are going for a swim in a big fancy pool. Your batchmates(& him) had already change clothes into their swimsuits while you're just in a plain white shirt and a short. Everyone was happily swimming while you're just splashing waters around. While you were about to go out on the edge of the pool, someone suddenly pushed you in the middle of the deep pool.
