Rainy seasons's feed

I read it awhile ago and I don’t rmb as much but yeah. it’s straight and completed I think
basically the mc has a crush on her bsf but he gets a gf and she gets all depressed. Then she starts like fake dating this popular dude he has blond hair or smnt. And he likes this older women but it doesn’t work out. They basically help each other and then she like falls in love and confesses to him at the end and it’s kind of left open ended and there were no more chapters after that. She had brown hair btw.
The thing is it’s colored in a manhwa style but it takes place in japan I think.
