Your batchmates had planned to go into a hotal with large swimming pool and needed everyone to go so you don't have any choice but to go.

while everyone was swimming, you just sat on the edge while splashing your feet on the water, wearing only a plain white shirt and a black short. Seungcheol noticed you and came besides you but on the water.

“Ey, why don't you join us?” He asked while rubbing your knees that was underwater with a smile as his dimples were showing.
