help me find this one bl

okay so i don‘t remember everything but i think the protag was the seme and he had like curly/wavy black/dark brown hair and his ex was a news reporter(if i remember correctly). the mc was still obsessed over his ex and he waited outside his ex‘s workplace because he wanted to see him so badly and i think the ex was avoiding him on purpose.
