Joshiochi! 2-kai kara Onnanoko ga... Futtekita!?

Sousuke lives in a cheap, run-down apartment and sees few advantages to the building beyond its beautiful landlady and the cute woman living directly above him. One day, a suspicious creak in the ceiling becomes a bizarre disaster when the second-floor apartment gives way and his upstairs neighbor crashes down on top of him. The accident brings them much closer than either expected, and life becomes even more complicated when the landlady is drawn into the same tension. Under one roof that is literally falling apart, Sousuke finds himself caught between two women and feelings that go far beyond ordinary neighborly affection, with every attempt to restore normality making the triangle more awkward.
