The setup is pure comedy poison: two people who actually hate each other trapped in a fake marriage, forced to share an apartment while hiding it from their entire school. The joke writes itself, except the show keeps pulling the rug out by making them genuinely good at domestic life together. By episode three you're watching them bicker over laundry and realize you're rooting for them to stay married, which is exactly when the show knows it has you.

Saito Houjou's inheritance comes with a catch: he needs to marry before he can claim his grandfather's company. The bride is already decided. It's Akane Sakuramori, the one girl in his class he genuinely can't stand. She returns the feeling completely. Neither wants the match their grandparents have pushed on them, but they are pressured into going along with it, and they agree to keep the marriage hidden from everyone at school. Living together under one roof forces them into constant proximity, and at first they are always at odds. Slowly, the walls they've built start to crack. As their days together pile up, they share more fun moments and begin to understand each other. Saito discovers a cute side of Akane he never saw before, while Akane starts to face feelings she has kept to herself. The result is a romantic comedy about two stubborn people who can't quite be honest with each other, sharing a home and a secret.
