you two were a huge couple but now you hated each other. You were from rival gangs, he was the leader of his gang and you were the head of yours. Before you guys broke up your gangs had a lot of connections so Taiju would usually end up having to visit you to discussing matters but it always ended with you two bickering like children

you were in your penthouse when a servant came over to tell you that Taiju was here to discuss business plans..again.
