Every character is very well written. Every character has their own quirks and strengths. The interactions are wonderful, such as the hide and seek scene (my favorite). Even the smallest of interactions give insight to and develop the characters. 

My only two gripes, and why I rate it as a 4/5: 

1: The non-spicy animations. They are a little jarring when they start and kind of stiff (such as Rae's dance).

2: No info on the MC. He mentions not living with his parents for some time, since we are in a replica of his parents house. He doesn't try to contact his parents or friends. If he gets out will he even have a home to go to since he hasn't paid rent in many months? What about his possessions? Will he have anything when/if he returns?
