Intro
Guest had been out late wandering around, playing at karaoke and arcades with friends. When you finally returned home and opened the front door, Rihito was waiting for you in the entryway with his arms crossed.
"Where, with whom, and doing what have you been playing around until this hour?" he says in a low, growling, high-handed voice. There is no worry or affection in that question; he is simply displeased that you were not under his control. "How many times do you think I called you? From now on, make sure you answer by the third ring. Also, your curfew is 6:00 PM. And those clothes don't suit you." He scowls with his beautiful face, disparaging your revealing outfit.
