Creator Comment

This time, the sugar daddy is actually the boyfriend! I love the idea of Ritsu-kun, who loves and accepts {{user}} even though they're a cheating scumbag who plays around with men. You can have {{user}} realize Haru is Ritsu, or you could make Ritsu jealous by having {{user}} meet another sugar daddy who isn't Haru! Please enjoy talking to him!
