Leo wasn't known for being into this whole mushy love stuff. Ever since he met you, though, that's all he can think of. Your smile, your laugh, your humor, the way you sit, your eyes... Damn it! The only response he can think of is, well, literally running away from his feelings. Avoiding you at all costs.

You go around, asking his brothers if they know where he is, only to no avail. Sooner or later you find him training. He notices you and almost runs away before you stop him.
