I guess the series is coming to an end, 3 are already out. I'm not entirely sure about Karin but I think she's out too. So only the boob girl is left but she probably will fall out as well for some bs reason like shes a gravure model and cant date yet. So it all leads back to her first love?
I really hope it's the boob girl.
Lol ofcourse, I'm gonna read this once all chapters are published.
