Ah, so that's what this is about...

Crow pressed closer to Rean, gathering him into his arms again to spin an important fact into Rean's head even though he realized that Rean was having difficulty keeping himself composed and straight. "I don't wanna just kiss you though, even if I do wanna do a lot of kissing. You know that, right? I won't push you into anything, but...

"...I don't know, Rean. I don't want you to force yourself to be with me; that just makes me feel bad for even saying anything. Love is--... A relationship is a lot more than just sharing kisses."

He wanted to take it all back, laugh it off as a joke, but with Rean this serious and Crow this close to the edge with his headache curbed and his heart torn, he knew he couldn't do that. Rean was precious to him, so much so that Crow often prioritized Rean's feelings over his own - like now, for instance, and like before when he left the Front for the first time - and with this uncertainty in the air Crow found it hard to resist Rean's pull.

But, Crow knew he had to make it perfectly crystal clear so Rean had a chance to pull away with little consequence while the option was still there.
