This love scene occurred immediately after the girl saved the boy from plummeting off a cliff. Obviously, after that kind of shock, some kissing is in order.
What I love most about this is it shows the lead-up, and the aftermath. For the actual kissing, you'll have to use your imagination. Because no one wants to see that. No one.
It reminds me of when my brother and I tried to figure out how TV actors were pretending to kiss, because obviously they weren't really kissing. How did they hide the thin screen that was keeping them safe from awful person-to-person lip contact?
