base on my own understanding little potato got kidnapped because he's father is a probably a leader of mafia or gang. and he's father is the one who killed papa wolf 's brother, dunno if it's biological or just brotherhood u know from the same gang. and when papa wolf know the true identity of little potato i think he's probably ok of keeping him because little potato is just a baby so maybe papa wolf thought he shouldn't include little potato to they're gang quarrel, and their's a chapter when little potato meet he's biological mother just forget what chapter it is though
sorry ( ̄∇ ̄")

I love this story......I MEAN LOVE IT..IT HEALS ME.....but I really want to know about the main plot....about his biological parents his past everything.... sometimes it just feels like we are getting all type of side stories(I love it tough and I am here for it) but I really really want to know what happened.....my brain just keeps making stories of its own...I wanna know ╥﹏╥
