this ome has stuck with me for years. really beautiful story, art, plot, characters, everything
manga not manhwa
https://www.mangago.me/read-manga/yakusoku_no_neverland/
but also the manga to one of my favorite psychological horror animes
they grow up at the end, but kings maker focuses on the actusl transition to adulthood and the story is balanced between adolescent to adult, and each age serves its purpose in the story
Idk if this counts but https://www.mangago.me/read-manga/koishite_daddy/ is the story of the father and stepdad while https://www.mangago.me/read-manga/love_kids/ is the story of the kid, but you don't see him grow up, he's just an essential character in the first one and the main focus of the sequel. I hope you find what you're looking for tho!
Thank you all for the recs :)
Does anyone have any manhwa with child MC’s that actually grow up? I’m not a fan of how most of them stay children.
