Searching for bl, please help

I can't even remember how they looked like, but they were boss (top) and employee (bottom) and fuckbuddies and bottom found out that the boss bought bracelet and he got happy thinking it was for him, but actually it was for someone else and it was very angsty i liked that ╥﹏╥ i think later employee quits his job to move on but boss follows him and regrets how he treated him. It could have been either korean or chinese manhwa.. Please help me find it <3
