Is there a bl out there with manga level plot and webtoon style art

do u mean the mellow feeling u get from most bl mangas?

Yes!! Manga bls mostly have actual deep plot and are unique

Well it's Paljae for me

i liked this one more than some other BLs for the characterization

for me, reunion, spring the color of love and any works from yang ilwoo and i’s author are the closest
