Touko is a single mom who's out to prove she doesn't need a man in her life. Unfortunately, her next door neighbor, Yuki, is a good-for-nothing college student who drinks, fools around with girls, and skips class, generally setting a terrible example for her daughter, but the two end up involved anyway with an agreement to help one another. I really love the setting and would honestly be thrilled if it never got romantic and was just the story of how her younger neighbor became a coparent to her child, but I'm sure it'll be cute as a romance, too. Trigger warnings: cheating, suicidal ideation
