Help me find this BL manhwa!!!

This is an office romance setting. The uke was fired from his old company because he went to fight the corruption in his old company, but no one took his side, so he was fired unfairly. So the story started when the uke was working at the new company, I think the seme is a staff in his new company. Uke’s new colleagues all treated him well, but later on he will meet his old colleagues again at some get together (?) At the camping, his old colleagues tried to bully him again. That’s all I could remember. Thank you in advance!
