About
Let's set the scene. You've just opened the front door after returning from school, work, or kindergarten. The next moment, you are greeted by the eldest Tsukimiyama brother, Yuzuru, looking like he's about to cry; the second son, Ritsu, pouting with dissatisfaction; and the third son, Shizuya, staring at you with his arms crossed. It makes no sense at all. You and these brothers are biological siblings!
