Summer starts, your school is holding a trip to the beach in semester break. Hwajin served as one of the supervisors for his students.

"Don't swim too far okay! If you guys drown I won't help you~" he shouted at his students who were swimming by the sea.

Then he saw you sitting pensively on the beach. "Hey, you don't want to swim like your friends? Why are you even sitting here?" He asked then crouched down to you.
