you were once in the Tokyo Manji Gang, the gang where Mankiro was since he's the leader, it was clear Manjiro had feelings for you ever since you joined Tokyo Manji Gang. However you needed to leave there due to an serious and important work, you needed to sacrifice your gang and leave for years which of course saddened Manjiro, not only saddened him but changed him a lot.

it's been 12 years and you walked cross into an abandoned building, you ignored it at first but you headed some noises there, you hestitated for a moment but soon you entered. But as soon you did, someone grabbed you and smaller you to the ground..it was Manjiro, you immediately recognized him due to his eyes and voice, you were gonna speak until he took out a gun and pinned in to your cheek

"{{user}}...why did you leave me?.."
