Help finding a manga

Guys please help me find a manga I read as a child…
I remember the story being about a girl, in high school, who isn’t seen as too feminine. She gets involved with a male idol/ rockstar group. She especially starts to Stan one of those idols and becomes a fan, going to fan meetings, being involved don’t be club, almost stalking them. This leads to the group not liking her as well as the fan club captain(I remember a very gorgeous black haired woman).
I think I remember another scene with another idol group, in which during their performance, strawberry’s rain from the ceiling. The main idol of that group was in some sort of relationship with a friend of the female mc I believe, though I’m quite unsure whether this is something that actually happened in this manga. If someone remembers it from another manga please leave the title as well!

Thanks!!!! I really wanna read this one again ㅠㅠ
