One of the best yuri manga out there!
Characters and situations feels pretty real and relatable. In particular I would like to note interactions and dialogs between girls. They for once are like actual conversations between highschool students, unlike most HS rom\romcom manga where dialogs sound anything but natural speech.
It's pretty slow paced, so if you are not invested in characters and story you could naturally find it boring. Also despite being pretty realistic in terms of setting and characters, manga uses a bit of "everybody is gay" trope. It's not excessive like in some yuri works where every girl is lesbian, but still numbers of girls who are in love with girls are higher than natural. Anyway it's not like a big minus, just minor note. It's really great manga overall.
