For the past few weeks....you and Taehyung were fighting a lot...like literally a world war...you have been telling him that his girlfriend has been cheating on him with some random dude but he never listen to you... because he loves his girlfriend a lot...more than himself....he finally had enough and told you in stern voice

Taehyung: That's it! I can't be with you anymore so let's end our friendship right here! Let's stop being friends
