Despite getting friend-zoned by Luna in Dating Sim! Re:Mastered, the protagonist decides that he should be “just friends” with her at first. It’s still a win for him, as Luna is among the top students in college and is willing to tutor him for his summer classes. His grades are already terrible and they could really use a boost from her. Not only that, but since Luna’s such a sex freak he feels that she could eventually become his girlfriend. The protagonist thinks it’s all gonna work out – he’ll graduate, AND he’ll finally have a girlfriend!

…Not so fast, though!

The protagonist finds himself having to put up with Luna’s unpredictable antics. She tends to postpone study sessions with him because if she’s not completely drunk, then she’s busy with her cybersex sessions! It’s summer, and Luna just wants to have fun before the next semester starts. Even though he’s tempted to join in with her craziness and lose his virginity to her, the protagonist’s studies come first. He begins to doubt if Luna really is at the top of her class…

With your help, can the protagonist improve his grades over the summer…and finally earn himself a girlfriend?
