This line really gets to me: "You don't have to say please. You know. Every time. It's okay." Robin's been so carefully polite and considerate, and Angel comes out with this perfect sentence. It fits just right, and is also so much in tune with Gojyo's canon personality if he were in a similar situation.

Also, each time you make the sex utterly fantastic, and more loving (oh, yes, you two do love each other, it's so clear in how you make love) each time, just right for the characters and oh so perfect.
