would love to help can you maybe give more details?
Was it Japanese (manga), Korean (manhwa), or Chinese (manhua)
Was the guy an ordinary high school student, or was he an idol/celebrity/duke/prince etc?
Did she literally call herself his fan/oshi, or do you just mean she adored him like a fan?
Do you remember how he died? (Car accident, illness, murder, etc.)

I need help find this manga. It was a story about this girl whose bf died and she ended up back in time.And in this timeline she is trying to protect him from dying even though they are not dating. Their dynamic was super cute bcoz she was a dedicated super fan of him and he was just shy about how someone could like that. I would love to read it again (=・ω・=)
