Watarin, the manager, is hiding a secret: He's been having sex with three girls. But finally, the truth is revealed to everyone! "Not just with my sister but with Yuki too?! Watarin, you're annoying!" "I knew you had that kind of relationship with Haru but with Mizuho too..." Shocked by this revelation, Haru runs out of the room. Watarin chases after her. He finds Haru on the beach. "Who's the best out of the three of us?" Watarin is pressured by Haru but Yukina and Mizuho, who had come looking for them, arrive and they decide to go back to their room... Yuna proposes... "Watarin is needed at the dorm, so why don't we just share?" "As of today, you're not allowed to have him all to yourself!" And so begins the harem play with the girls.
