This comment will be long, I'm sorry. If you haven't read them already:
https://www.mangago.me/read-manga/take_me_high/ (out-going x introvert)
https://www.mangago.me/read-manga/unrequited_love_rendezvous/ (silly goose x serious, scary-looking sweet guy)

https://www.mangago.me/read-manga/gyaru_kun_no_koi_wa_kitto/ (in love silly goose x oblivious reserved boy)
You can already see a pattern. I love silly geese. MCs who are adorable and kinda dumb. They are very dear to me.
https://www.mangago.me/read-manga/pheromone_say_otherwise/ (oblivious x in love)
https://www.mangago.me/read-manga/the_moon_painting_alchemist/ (sweet capable genius x awkward "I'll protect him at all costs")

https://www.mangago.me/read-manga/yuutousei_wa_unmei_no_akai_ito_ni_sakaraitai/ (in love x oblivious)

https://www.mangago.me/read-manga/faded_first_love/ (silly goose x serious)
https://www.mangago.me/read-manga/hungry_souls/ (loud and out-going x quiet and reserved)
For the next ones I can't remember the tropes, but I know they're not toxic:
https://www.mangago.me/read-manga/the_art_of_taming_a_tiger/
https://www.mangago.me/read-manga/one_small_step/
https://www.mangago.me/read-manga/a_season_of_dusk/
https://www.mangago.me/read-manga/family_now_and_forever/
https://www.mangago.me/read-manga/love_at_first_fright/
https://www.mangago.me/read-manga/between_the_stars/

Are there any hidden gem/not so popular bls with trope :
Grumpy x literal sunshie
In love x super oblivious
Outgoing x passive, shy, introverted
Hotheaded x his calming pill
Unsure, hesitant x want to take their relationship further but willing to wait forever
I'd love if you could give me additional tropes based on what is listed! If it could be helpful, im into fluffy stories, or stories with happy ending. I don't mind if it has misunderstandings, but if it's too frustrating i'll just quit reading altogether also, i really hate mls who is a jerk, and takes everything for granted (im saying this just because mls usually are some rich assholes). Im not picky about the personality actually as long as he is not a jerk, but if he is a simp/down bad it's a bonus yummy yummy
I also like bls with adorable ukes because it just heals something in me! Ex : dan yi rim from surge towards you. Smut is okay, shonen ai is also okay. Lastly, idk if i should even mention this anymore but no rape/noncon please!! Other than that, im fine with omegaverse, guideverse, fantasy etc.
Thanks a lot!!!!!!!!
