I was just looking for something to kill time but this manga really surprised me! It just gets better and better and as of now ''chapter 54'' it's freaking amazing. It's not the usual reborn manga like tales of demon and gods, no this one is different. The main character is reborn in the past as another character while his true self still lives. The main character changes as he is born with other parents and learn lots of new stuffs while trying to change bad things from happening, helping his old self in secret while hiding his intentions/powers! 

If you like a really OP main character with some romance and a unique and good story then give this a try! the only con with this manga is the art which could be better but it's nothing that really bothers me.
