i need pain rn, send recos

Someone please give me unrequited love stories, where the Person A is crazy over Person B. But Person B ignores or even hates Person A. And then Person A gets tired and eventually gives up. Person B then realizes Person A's worth.

Could be manga/hwa/hua, preferably straight romance, but could be bl, too if you know something like this. And ik this is weird and too much for a request, but please recommend me something not tragic.

Thank you!!!!!!! (▰˘◡˘▰)
