ML Offers to be Used by FL OR FL Uses ML & ML is Willing

Ep 7 - ML offers himself and tells the FL she can use him all she wants, and he means it. 

Ep 9 - I'm willing to fight the tiger along side you. I'm willing to stand by your side, serve as your advisor, and become your right-hand man. Together, we'll bring down those who deserve it.

Ep 13 in particular

ML possibly, but he isn't selfless.

SML for sure, and he is selfless.

Ep 13 - ML overhears the FL bluff to his father that she is using him. The ML is upset by her words, but pretends he didn't hear. From things he said and did separately, it's still clear that the ML has feelings for the FL and is willing to go to great lengths (even sacrificing his life) to help her. 

Ep 18 - I will be your eyes. 

Ep 33 (revealed in Ep 34) - Help her fan the flames.
