oohh good question... I'm not sure but:
Based off vibes I would recommend the mangas Skip and Loafer, and Hirayasumi, and I have heard that if you like aslfua you'll like the comics The Students of Illip Arts High and Spirit Fingers but I can't speak for those yet since I haven't read them!!
For dramas, Crash Landing on You has a similar dynamic to cheolmiae and 2521 has similar vibes to aslfua (but I have a lot to say about the ending amongst other things,,,)
If anyone else has recs, please feel free to add some!! I don't think I have any super original recommendations but I hope these helped!!
