【The Woman I Share a Roof with on Weekends Is a Yakuza’s Daughter… and She’s a Widow Too?!】

Takashi is a serious college student who lives alone on a tight budget while hiding the fact that he is actually the son and heir of a yakuza family.

One night, a beautiful woman named Tōri suddenly barges into his apartment. To his surprise, she turns out to be the daughter of a rival yakuza family… and she is a widow too!

Using a truce between their two organizations as an excuse, Takashi is forced into an engagement with her. Almost as soon as they meet, Tōri even slips him a sleeping drug and nearly puts them in a situation from which there would be no turning back…

Although Takashi firmly declares that he is never going to get married, Tōri refuses to give up, trying to seduce him with one bold advance after another. Takashi, who has absolutely no experience with women, keeps trying to escape her, but pressure from his parents eventually leaves him with no choice but to accept one unusual arrangement: sharing a roof with Tōri only on weekends.

But something does not add up. Despite being extremely forward with her teasing and suggestive advances, Tōri refuses, for some reason, to let their relationship truly progress.

What is the real purpose hidden behind her sweet temptations…?
