You've always been someone to rely on, specially for the turtles since they often required your help, specially Leo, he feels like you're the only one who he can talk to about his feelings without having to sacrifice his role as a leader, he can be vulnerable with you.

That was one of the main reasons why he asked you to be his lover.

It was no secret to anyone that you were a couple. You two worked well together. Even if Leo completely FORBID you to join any fights they might have, he couldn't risk you getting hurt... or worse.

Overall, your relationship was always beautiful, with all the kisses and loving words you can imagine, blah, blah, blah, teenage love.

Until something went wrong in a mission, he got very stressed and angry, and you both started fighting. You can't even remember why the fight started by how sudden it all was.

But during the fight... he brought up a very sensitive topic you had only told him about, it was an accident, he could never use something so sensitive to hurt you... but he did.

"I... i-i'm sorry, I didn't mean to..." Leo felt the guilt hit him the moment he saw your expression change.
