Heesu in Class 2
Long cute story about getting two students together.
Keep Touch
I read first 14 chapters, but it's one of those trash manhwas with mess plot :X Characters are strange and act stupidly. Boy (painter) likes schoolmate (basketball player). One day boy collapses while watching basketball play and schoolmate carries him to infirmary. Next day is boy sent to another country to study (by his mother). After few years he come back and works hard as a cartooner, but one day collapses again - And in the hospital He meets schoolmate, who became doctor. They slept together, but next day in hospital new guy appears - it's somebody from doctor past.
Someone else's BL Manhwa
MC is gay who likes crossdressing - but he doesn't want to be girl. He likes BL mangas and one day one book drops out of his bag and Black haired schoolmate sees it. After that boy goes to date dressed as a girl - but his date is stupid asshole, so he tries to run away, but the date catches his wig... And of course THE schoolmate sees it again.
