The bot really have this habit to stalked the top and one day he saw the top looking extra fine and decided to follow him bcs he thought the top want to go clubbing or something but the truth is the top went to a warehouse and like kill someone ( I don't really remember this part but it like how gangster deal with people ) and there like bodyguard something like that and the top caught the uke and force rape him. To sum up the top blackmail him and really control the bot can't go anywhere we asking him and they need to eat lunch together. Extra : the top didn't really hasitet to punch or crush the bot and he's kinda violent
