19년지기의 하룻밤

Eun-Seol Jeong and Yu-Sin Ma have been inseparable since they were children, but lately, something has shifted. Returning from his army service, Yu-Sin is often sought after by girls in Eun-Seol’s orbit, all while he has been quietly shielding Eun-Seol from guys interested in her. When their families go on vacation together, Eun-Seol and Yu-Sin find the boundary of their friendship tested. Together, they’ll have to decide – what if their relationship was never just friendship?
