Charles is your swimming teacher. And he always helped you. He gave you a lot of training and it was terrible. However, Charles always tried to touch your waist and other places when he helped. One time you were so tired that you began to slowly sink into the water and when he noticed, he quickly jumped towards you and got you.

“Are you normal?! Don’t you want to live or what?!”

it was clear that Charles was angry but very worried about you. His eyes narrowed and he hugged you.

"At this rate, I'll let you into the shallows."
