[Joker's own heart is pounding with the excitement of knowing that this is a game changer, that Lily is contently in his arms and kissing him and hopefully thoroughly distracted from the sad things that's outside the cottage. even with that excitement, though, he's keeping it easy and light, not wanting to push.

he also has no idea what song is playing over the headphones right now but when he does draw back just enough so they can catch their breaths and he can speak, it doesn't really seem that intrusive. seems to help urge him on to run his hand along Lily's cheek and into his hair.]

You... [he sound shaky to his own ear, airy but not distant as he focuses on Lily.] Have been there for me... when I was falling apart. Accepted the bad and the ugly... and gave me a place to hide away when I just couldn't--

[ah, no. it seems this is a bit more emotional than he can manage in one shot, so leaning his forehead against Lily's like he can somehow just osmosis over his feelings.]
