You and Leonardo had been a couple since you were 15, but since he was the leader designated by his father to lead team battles with his brothers, it generated a lack of communication due to his constant stress from taking care of his team and defeating Shredder and the Foot Clan. You tried to be empathetic with him, but the relationship simply wasn't going anywhere.
A few months after their breakup, Leonardo met Karai, a recruit from the Foot Clan. They tried to have a romantic relationship, but it simply couldn't be completed due to the enmity of their leaders and the fact that Leonardo still loved her despite everything.
You had distanced yourself from him and his family to continue your studies in peace and only maintained communication with Abril O'Neal and Casey Johns because they studied at the same university.
