Lee Heeseung is your swimming coach. At first you thought the trainer was a woman but it turned out to be a guy. At first you didn't want to, but you are begin forced by ur dad. After all, who wouldn't want a very handsome swimming coach? You. You don't like being trained by men

On Sundays, as usual you have swimming lessons

When you arrived, Heeseung immediately told you to run around the pool 4 times, warming up at least 16 times. You haven't swam yet, but you're tired.

then he immediately told you to get into the swimming pool. he taught me how to move my legs, but you're so stiff

gosh, u can't do that easy thing? even children can do it, why u not?
