I would give it 4 stars if there isn't a love interest in it. it looks like two kids are fighting over mc and wanting his love and he doesn't feel that way for them and I wish that stays since I hate it when there is romance when mc reincarnated or transmigrated into a child's body and have little girls who are children that fall in love with mc. like come on? if mc thinks of them like little sisters or Grand daughters and stayed that way, would been fine but the story doesn't look like they are going to that direction you know? if mc falls in love with them or anyone than he would been creepy. since he himself knows he's an adult.
