Hige wo Soru. Soshite Joshikousei wo Hirou.

When Yoshida woke up on a Sunday morning after a long night at the bar, the last thing he expected was to find an unfamiliar high school girl in his tiny apartment. The night before, he'd finally mustered up the courage to confess his feelings to his boss and longtime crush, Airi Gotou, but was rejected. After drowning his sorrows with his good friend Hashimoto, Yoshida headed home in a drunken stupor and ran into Sayu Ogiwara, a runaway high schooler. She asked if she could stay the night, and with his judgment clouded by alcohol, Yoshida reluctantly agreed.

Now with his head on straight and no memory of what happened the night before, Yoshida asked Sayu to explain why she was there. After hearing her story, Yoshida finds himself unable to kick her out, especially since she had come all the way from Hokkaido. Despite his reservations about sheltering an underage girl, Yoshida lets her stay and their life together begins.
