Hm...I want to like it, but this manga always has this "enough playing around, time to find a husband" vibe for me. At least with most pairs.
On the contrary, it plays with the trope I think.
It's like the characters are lying to themselves by talking about boyfriends and husbands, and the readers know it
And anyway, I doubt we will see them grow up into adults.
Or they will become like the girls in Maka-Maka from the same author.
I think the author does a good job of having a mix of relationships.
Some are just friendships
Some of them are definitely just the like class-s intense friendships / preparing for eventual heterosexuality stuff.
Others are more like sexual exploration, but maybe not romantic
And then you got some just full-on gay romance, too.
I think that's an interesting approach to the yuri/class-s "it's a girl's school, so everybody's gay for now" setting.
I don't think it cheapens actual homosexuality, it just recognizes that there's a variety of experiences. Like the class tacitly understands that Ai and Chie's relationship is serious in a way many of the others are not.
Or then there's stuff like chapter 104, where Ayano would plainly be OK with dating Miyoshi for real, but Miyoshi just seems to think of it all as just playing around.
