I am very bad with titles... First FML is a diligent boarding yandere type who cooks, cleans etc. Second FML is exceptionally beautiful and does pt work or sleeps... and sleeps. They move in together and immediately just share one bed. There's also some other yuri relationships between upstairs kohai, first fml's sister, classmates in college. Follows them from freshman highschool to when they are looking for work after college as of latest chapter. HS was lax af, no uniform, only 3 clubs not mandatory. Also required dorms or staying in adjacent apartment with roommate. Think it was more 4-koma style

Maybe Futaribeya
