When I saw this on my feed I searched for the info and found that it's available on webtoon. I can't believe I haven't discovered this earlier! The art is splendid! It's free on webtoon so I'll be reading from there. This is an OEL BL webtoon, Omega verse, extremely colorful and beautiful art style (check it out on webtoon)
Note: I've only read the first synopsis.
It's also available on webtoon for free (and come to think of it, I don't usually read BL on webtoon, but it's an OEL series and the art looks beautiful)
