The MC here is ' a cute wild cat ' who needs TLC,
https://www.mangago.zone/read-manga/tamaranai_no_wa_koi_na_no_ka/ (short, cute BL manga)
https://www.mangago.zone/read-manga/classmate_relationship/ (a little bit of angst at the end but otherwise it's very funny and sweet, and i think you will agree that have a similar personnality/vibe than the main characters in Salt Friend.
https://www.mangago.zone/read-manga/leo/ _ Lovely !! Lighthearted and deep at the same time ? It's a BL with circle of friends.
https://www.mangago.zone/read-manga/don_t_leave_after_school/ _ a bit less of a slow burn, still Shounen Ai. MC meets his knight in shining armor in the most unexpected place.
I just finished salt friend i need some more bls like that
