I haven’t read PASSION will I still be able to understand this story?
Yes absolutely. I have read Passion, dropped it and never picked it up again bc both Taeui and Illay are just too frustrating but I REALLY REALLY LOVE RAGA. However, if you want to take a closer look into the relationships between the characters, Yuri's and Xinlu's background and social circle, you can read Passion first to know more
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.

this ome has stuck with me for years. really beautiful story, art, plot, characters, everything
manga not manhwa

but also the manga to one of my favorite psychological horror animes
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!
Any spoilers? Like does xinlu end up chasing after yuri?
yes!
