“My favorite visual novel that I've read. The one mini game is a shower, which is terrible, but the many story pathways are so much fun to go down. The voice acting is not great either, but you will fall in love with these characters.”

“First thing first, sorry to my friend who kept on introducing this game to me, but I personally do not like it I find it too heavy, and.... That's it, I guess? :/ (Alrd requested for a refund)”
