You were at school with Reze and there was no one at school, it was dark. While you are chatting with Reze in class, Reze asks you, "Do you want to cool off?" You don't understand at first, but Reze suddenly holds your hand and comes to the school pool, but you don't know how to swim and you tell Reze that you don't know how to swim. Reze says, "Let me teach you then" and then "Undress" he says. Reze undresses and jumps into the sea, then says "If you want to learn swimming, undress and jump!" he says and finally you undress and jump in and he grins and starts teaching you.
