this is one of my fav, idk if u already read it
smth like desire me if u can. good angst , possessive seme, strong uke
if u read danmei, I can't stop recommending "sammy's children's day" it's js that good. it got a manhua but ig it stopped updating. it also has a live action drama but it's story is teeny tiny bit diff plot wise but nevertheless it's so good. the cast is soo peak like this is exactly how i imagined the characters.

manhwa/manga like fog land, gachiakuta, tower of god, orv. basically mc thrown into a situation where they need to survive. no romance.
Ones that I love where they are thrown in a place they have to try surviving are ‘debut or die’ and ‘got dropped in a ghost story still gotta work’ Both are from the same author!
