Try the BL "Honey Bear"!
It's still one season complete, but the art is good imo.
Also recommending the good ol' Here U Are if you seek for a good plot and art.

One is not bl, it’s called Yeonwoo’s innocence, and it’s straight, but the mc is a male and a more of a softie boy and the FL is taller and more stronger mentally(?) and physically than the male, it’s good and the angst is *mwah*. You should read it if u haven’t read it before.
for action, I'm looking for something like Eleceed, Ranker's Return, Trash of The Count Family.. basically a system-ish books..
and for BL, i just need recs of books with good art that's it
