Hela's manga / #Action(4)

Another cocky male lead who knows better than anyone, who isn't phased by anything, who doesn't feel any fear, who controls every situation with a shitty grin and his hands in his pockets. The not human kind. Uggh I so want to slap that arrogant smile off you.

Goes back on time, gets revenge from all his enemies. Apparently complicated schemes, but everything goes smooth and easy. MC in control of everything, thought about everything.
