"Pamper me! Right! Now!"

On his way home from work, Tatemaru comes across his high school senpai, Miyama Yukihito. He's supposed to be this super perfect and talented person, but he's here in his house, lazing around, acting selfish. Seeing Miyama reveal a weaker side of himself to him, Tatemaru can't bring himself to kick Miyama out. Thus begins their domestic life together.
