Do new good loving romantic bl which has plot not all fuck genuinely exist nowadays? Why i...

um yes "Rainbow city" (there is some SA in chap 3, but thats it so it's best to skip, the rest is pure plot with a bit of smut mixed in in a few chapters, also slow burn)

little mushroom
breaking through the clouds 2: swallow the sea
memories of your breath
monochrome rumor
no moral

Murderer Llewellyn's enchanting dinner invitation

Its so good, it has no smut and is ver sweet (couple-wise)
The story hella dope too if youre into mystery and alot of angst

This one and its sequel are super cute.

There is a whole shounen ai genre right there. All the bl and romance without all the fucking.

But if you're specifically looking for yaoi bls: currently my favourite plotty bls are

Starstruck
(yaoi but with lots of unrequited love and yearning and so far the most explicit thing we got is a masturbation scene)

Ennead
(has a lot of smut and noncon in it but it's mostly plot and slow burn romance. Also incest but like it's Egyptian mythology so it's kind of a package deal)

Dreaming of the Dokkaebi
(this one has smut too but it's fairly well balanced. It's still a plot based story with its world building and fantasy elements.)

Dreadful night
(it's a horror game time loop. It still has smut and dubious consent but it's got a very engaging plot)

Daraku Kazoku-ron
(3 random people become a dysfunctial family of some sort. Very wholesome)

these are good examples of loving relationships but they also include smut:

and here's some that have more actual plot and no smut:

I fear I've read most shounen ais, the one you recommended, and mangas that were cute as hell... I've consumed it all I fear

They're ADORABLE I actually sobbed so hard at their story, they deserved their ending

WAITTTT I haven't tasted little mushroom yet

TYSMMM I missed some of these so on to reading now
