Ai toka Ii kara Dakishimete

Yuriko, 35 and single, leads a humdrum everyday routine of work and looking after her disabled father. At the kindergarten where she teaches she's treated as an old maid, and at home her father won't listen to a thing she says. And of course she has no plans to marry... after all, she's just going to live out the rest of her boring life here in the countryside anyway, right? But while she's lost in thought over it, she causes a fender-bender. She doesn't know how to react, but Sosuke, the man in the other car, tells her he'll forget it ever happened... if she has sex with him! But after she goes with the flow and "just does it," it turns out that he's actually the father of one of her students?! And as if that weren't enough, Takumi, her kindergarten's cheeky young chief director, arrives on the scene...? Thus begins a clumsy love triangle for a flawed adult who had given up on love.
