I assume this was his adult form, i think the light novel/webnovel has like a thousand chapters tho so it might take a while unless there's more time skips lol
Tho be hilarious if it ended with, his next life also being in some kinda 'fame'/industry role and he's like "one of my inspirations was [Past life's name]" or so XD unless he's satisfied at the end tho i'm sure being an actor for a few more lifetimes would be enjoyable if he doesn't try to be famous being in an idol group like BrownBlack
