After a drunken accident, Su Hyeon accidentally kisses someone five years younger and suddenly, that younger guy keeps appearing in his life. Embarrassed and clueless about what to do next, he starts avoiding him, but…
A tipsy stumble at a party leads to an accidental kiss between Su Hyeon (27) and Eun Ho (22), a cheerful and younger stranger. Mortified and utterly confused by his own reaction, Su Hyeon tries to avoid the persistent Eun Ho, who keeps popping up at his café, his gym, even his sister's apartment. As Eun Ho's sincere and playful advances chip away at Su Hyeon's defenses, the older man must confront his buried feelings and the self-imposed walls he's built. Featuring a refreshingly supportive sister and a no-nonsense best friend, this short-form romance proves that a little bit of chaos and a whole lot of heart can bloom from a single, unscripted kiss. A sweet, low-stakes journey of self-discovery and unexpected connection.
