Top actor Park Seha — what happens when his “ultimate bias” crashes into his perfectly ordered life?! Park Seha, the epitome of perfectionism and a top-tier actor. And Son Ji-eon, the dependable leader of a failed idol group. The two are cast together as leads in the queer film Brotherhood. Unlike their movie characters, who gradually grow closer while solving cases, the loud and lively Ji-eon and the quiet, rule-abiding Seha seem like oil and water in real life. But there’s one fatal secret no one knows— Park Seha is actually Son Ji-eon’s huge fan! Despite wanting to keep his distance, Seha finds himself pursued relentlessly by Ji-eon, who clings to him, begging, “Teach me how to act!” And the next morning… Seha wakes up to find himself in the same bed as Ji-eon.
