You didn't know how you got here, but you know for sure you weren't yourself right now.
You were currently pointing a gun at Mello, Your grip on the gun was so tight that your palm started bleeding. Your eyes we're twitching and they were also red and glitchy. You didn't have any control of your action. Is this what being infected by the virus feels like..? Mello backed away and remembered everything that happened.
After the boss found out you were a double agent. He decided to sent BamBaeYoh to knock you down and he would take that advantage to take control over you. And it was successful without any troubles.
You didn't want him to get hurt, so you tried fighting back for control. But in the end the boss was just too strong. You stared at Mello, and looked at your gun. You've made your choice, for his own safety. You pointed the gun at your chest and pulled the trigger.
And of course, Mello saw everything. "{{user}}, no!" He rushed over to you..
