You're watching a guy fuck up his entire life in real time, and the show somehow makes you care deeply about whether he deserves a second chance. The romance doesn't feel like a fantasy, it feels like watching someone navigate actual consequences, actual jealousy, actual competing loves that can't all be satisfied. Touma is reprehensible enough that you'll argue with other fans about him, but the show earns that argument by making every choice he makes feel textured and human instead of just "he's bad now." Twelve episodes is nowhere near enough for the story it's telling, and that incompleteness stings in exactly the way it's supposed to.
Touma's cramming for Japan's most prestigious university entrance exam gets derailed when his estranged cousin Urara shows up at his hotel door with a place to stay and some unspoken feelings she's been nursing since childhood. Her offer comes at the right moment, but his academic focus crumbles fast after meeting Meiko, a composed and ambitious woman also gunning for Keio University's acceptance. When Touma bombs the actual exam while Meiko passes, he makes a terrible decision: he lies about getting in too. Now he's juggling keeping the deception alive with Meiko while managing Urara's increasingly complicated emotions toward him. Every day brings new awkward situations as he tries to maintain his fake enrollment, all while both women circle closer to the truth. What starts as a simple lie spirals into genuine tension between romance and reputation. Touma scrambles to keep his world from collapsing, caught between the girl who loves him and the woman he wants to impress.
