Ask yourself two questions before going into this game.

1: "Have I dated a girl like Ame-chan before?"

And if the answer is yes,

2: "How well do I handle the flashbacks?"

This should help in setting expectations for a game that is deceptively wholesome when it comes to its core messaging, but accomplishes that through hitting very close to home in the process of telling you "Hey otaku! Don't be an incel, and treat your menhera GF with the respect she needs and deserves".
