Paixiu restaurant

All of these fit all of your requirements:

https://www.mangago.me/read-manga/3_ban_sen_no_campanella/ (I just read this today, and I really reccomend this one. It's short, but the pacing is good and it's very relatable)

https://www.mangago.me/read-manga/all_of_you/

https://www.mangago.me/read-manga/here_and_there_and_us/ (prequel)

https://www.mangago.me/read-manga/achira_kochira_bokura_no_are_kara_to_kore_kara/ (sequel)

https://www.mangago.me/read-manga/toumei_na_ai_no_utsuwa/

https://www.mangago.me/read-manga/minority_1/ (if you read ANY of these today, let this one be your first. It's so incredibly beautiful and it hits so hard. I didn't want to read it at first because the love interest was a bully, so I thought it was going to be a typical story of bully x victim, but it was so much more. PLEASE read it)

https://www.mangago.me/read-manga/a_shoulder_to_cry_on/ (a complicated love story between two troubled high schoolers)

https://www.mangago.me/read-manga/the_third_ending/ (A little more on the light hearted side, but the angst and romance is so good. Every time I read it, I still get the same feelings I got the first time I read this one.)

https://www.mangago.me/read-manga/tales_of_seol_gongchan/ (Again, it's one the more light hearted side, but this one was so cute and unique. It's a supernatural BL)

https://www.mangago.me/read-manga/ways_of_parting/ (Read on Bato . to for better and clearer translations) (This story has me crying so much every time I read it. The plot, the characters, the development is so beautifully done. And all the characters are so likeable.)

Hope you find them to your liking

Hope all of these are to your liking, they should meet all of your requirements (also, I put detailed descriptions when I initially tried posting this comment, but it didn't post 'cause I accidentally exited out of the tab I felt my body leave my soul right there and then

Ps. If you want clearer and better translations, I suggest reading "Ways of parting" (2nd link) on bato
