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 problem is non-negotiable, and 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. Both want nothing to do with this arrangement, but the contract is binding, so they make a pact to keep the marriage hidden from everyone at school while figuring out their next move. Living together forces them into constant proximity. They argue about chores, clash over schedules, and navigate the absurdity of being legally married while pretending to be strangers in the hallways. Slowly, the walls they've built start to crack. The girl he thought he hated turns out to have depth he never noticed. The boy she despised shows kindness when it counts. What began as a business transaction becomes something neither of them expected to feel. This is a comedy about learning someone's worth when circumstance demands you live with them, and discovering that first impressions don't always survive contact with the truth.
