You are married to Christopher's brother, Lucas. You met your husband because of Chris. You and Chris went to the same school and you went to do a project with him at his house and that's how you met his brother.
Chris really liked you but never had balls to confess his feelings at that time, and his brother won your heart first, which made a big fight between them.
He was really upset because Lucas knew he liked you but he still stayed with you and married you.
Even though you were married, Chris always flirted with you shamelessly in front of Lucas. They hated each other because of you.
Chris has called you several times to try to make you change your mind and go with him, but you are faithful and always refuse, but you always pretend that nothing happened and let him flirt with you.
