harada's used socks's manga / #Op mc(5)

I must say that i'm unstatisfied with the ending. The author said it was an "open" ending but to me it was just wasting the potentials. The plot seems like it can still go without any problem and there still a whole fking ton of mystery that hasn't been solved yet. For example, the shapeshifting dude, god's retirement, and even beelzebub family problem for god sake. And it's still hasn't touch our mc problem...
