The joke lands before you even understand it's a joke. Kenji thinks he's living with a guy, Hikaru thinks she's a guy, the show thinks you're buying it for five seconds before the premise itself becomes the comedy engine. Every conversation is built on this collision of what everyone assumes versus what's actually happening. The romance doesn't sneak up on you because the show never hides it. The real pleasure is watching two people figure out who they actually are while pretending they already know. That takes more writing skill than most comedies from this era bothered with.
Kenji Aoyama dreams of becoming a manga artist, but his cramped apartment and meager income make it impossible to focus on his work. When a mysterious boy named Hikaru shows up asking for a place to crash, Kenji reluctantly agrees to share his tiny space. The arrangement is chaos from day one: Hikaru eats all the food, creates constant noise, and generally makes Kenji's life harder. Then Kenji discovers the truth: Hikaru is actually a girl who was raised as a boy and has nowhere else to go. Now trapped in close quarters with someone he never expected, Kenji has to navigate an awkward living situation that keeps blurring the line between annoyance and something more complicated. As they learn to coexist, their daily struggles and unexpected moments of genuine connection begin changing how they see each other. What starts as an inconvenient arrangement becomes something neither of them anticipated.
