This little moment is so beautiful. Look at his eyes.
She kisses him and for a brief moment he watches her. He needs that tiny moment more to realise and accept that it’s happening. The woman he loves, who he would go to the end of the world and time for, has opened her heart to him. He promised to win her heart without trickery and that’s exactly what he’s done. It’s real, it’s happening and so he closes his eyes and loses himself in the moment.
