In a calculated power play orchestrated by Tabuchi—the wealthy CEO father—his lazy son Koichi is set up to marry Nao Jinguji. Despite being on the cusp of 30 and perpetually glued to his phone instead of working at all; Tabuchi decides he must force a match to ensure his heir finds a wife. Nao is the beautiful daughter of a partner company manager. Though initially resistant to this forced union against her will due to Tabuchi’s authority figure status,
she agrees under strict terms: she cannot sleep with anyone until marriage. A year later comes their wedding night. Koichi is eager for his first intimate encounter but suffers from performance anxiety and can't get hard!

The truth is, this marriage was merely a sophisticated ploy for Tabuchi to claim Nao as his own property. While Koichi is away, Tabuchi meticulously trains and molds Nao into a lustful daughter-in-law who craves his cock and eagerly anticipates being taken by him—even when Koichi returns home! Discover this scandalous domestic drama where the husband is just collateral damage in the father-in-law's greedy pursuit.
