Synopsis

Katsuragi Hayama (Nikaido Fumi), a happily married housewife of around 30 years old, is suddenly told by her husband that he has another woman and wants a divorce. Upon storming out of the house, she ends up being pickpocketed and as a result finds herself penniless and practically homeless. While she’s camping out, she runs into rich high school student Issei (Maeda Gordon), who offers her a place to sleep, but only if she partakes in a game. Left with no other option, she reluctantly agrees and ends up moving into a mansion where she is obliged to play the games he challenges her to in order to settle her debts.

Adapted from the manga by Tachibana Oreko.
