HELP, LOOKING FOR A PROMPT, WHAT TAG DO I USE TO FIND THIS PROMPT

help me please, what tag do i have to use to find this specific prompt where chara1 is really into chara2, but chara2 keeps pushing chara1 away for different reasons (most of the times it's because chara2 has a crush on another character) so chara1 decides to give up because they feel like they will never be reciprocated, but chara2 instantly becomes interested in chara1 when chara1 has already lost interest, chara1 has already decided to give up so chara2 has to work their ass off to earn their attention again. Is there a tag for that? if not why not? HELP PLEASE 😭😭
