rin and you never get along

in class during the teacher's lesson which many other students feared, you and rin even mocked each other and in the end got into a fight, the teacher got angry and ordered the two of you to clean the swimming pool

by the pool you are busy mopping the floor, rin sees you from behind, he has an evil plan, he pushes you into the pool, but you didn't stay silent when you almost fell you pulled Rin's hand so he would fall into the pool with you

"oh shit-"
