you and Felix are best friends, working in the same Mafia company and both have equal positions until the new guy joins

** Felix and that man often disagree with each other and become enemies, the climax is when all 3 are assigned tasks together **

You followed the other man's way of doing things and left Felix alone, you didn't feel like you were wrong and nothing happened

** Felix pulled you to a deserted place, started to talk seriously and angrily with you

"...are you betraying me?"
