I was reading a manga awhile back, it was a romance, shoujo, school life type of manga. I only remember a little bit of it and it's pretty basic, something you would find in a lot of shoujo manga but here it is:
It's about a girl ( she is very calm and doesn't seem to let her emotions drive her actions) who becomes friend with this guy, and I'm pretty sure I remember that he's the delinquent type and she's the class president or something. Anyways, they're friends for some time, it's pretty mellow, but then the girl starts falling for him and she eventually confess, but he's in love with an older women who's their teacher and whom he also knows personally, but it turns out that that woman is getting married so he can't exactly tell her he loves her. After the girl confessed and the older women got married, the guy starts to slowly fall in love with the girl and they start dating, but eventually they start to get a bit bored of going out and they don't think that they seem like a real couple, so they break up. But the girl still has feelings for the guy ( actually the guy still had feelings for her too, they just didn't really know how to be a couple) and in the last chapter that I read ( it was ongoing at the time ) she declares, in front of the whole class, that she will make him fall for her again, and he tells her to go for it ( or something like that )

That was a freaking long explanation, but it has seriously been killing me that I can't remember, and it's already been about a year of two since I found it.
Please help me🙇🏻

Do you remember approximately how long this manga is? And recent or older? I feel like I've read this too!
