Doyeon

Nahyun, afraid of water and unable to swim, has just signed up for swimming lessons in the hopes of overcoming her fear. There, she meets the attractive but rumored to have a shady reputation swimming instructor Cha Jaehwan. Although immediately attracted to Jaehwan, Nahyun pulls back quickly because she believes some men just aren’t in her league. Yet after spending time together, and after a number of rumors swirl about them, she impulsively proposes a one-nighter with him. After that night though, things change significantly when Jaehwan reveals that Nahyun is actually his first.
