To you, I'll be staying at Shiori's house tonight.

After several years of marriage, a ronin student named Kawai comes to live next door to the Shiraki couple, who are living happily together. Kawai fell in love with Yuko from the moment he laid eyes on her, and openly confessed his feelings to Yuko, a married woman. Naturally, Yuko refuses, but one day, smoke overflows from Kawai's house. Yuko rushes to put out the fire... Kawai collapses and says, ``I can't forget Yuko-san after all.'' Yuko feels that she can't concentrate on her studies if things continue like this, so she leaves a fake letter and dinner for her husband and heads to Kawai's place...
