“Wait, why is this dream so vivid… huh?” Upon opening my eyes, I see Kang Seung-won, my unrequited love of 11 years, right in front of me. We're in the same bed, and even worse—he's completely naked?! The problem is, I have absolutely no memory of last night. “It’s actually for the best. Let’s just act like nothing happened.” “Oppa, you can’t just leave like that! What happened between us last night?” Due to one erased night, the end of this long-time crush begins to head in a very unexpected direction.
