Reincarnated into a child - male protagonists

Main character has lived many lives. He’s a baby to 6 years old atm.

He has powers related to his past experiences, and they help him grow in fame towards being a celebrity/actor.

Same artist as who made me a princess

Cute childhood best friends that are reunited when older kinda trope.

Ordinary girl x rich boy

I mean usually this would be romance but one of the mc is a male and their a child so it fits to me :P

Mc failed his path as an actor. As his looks and acting are just average

He goes back in time and decides to get famous while he’s still considered cute and a child actor
