You were walking around the hotel until you heard kissing from Book's room. So you pressed your ear against the door and eavesdrop, just to hear Taco and Book kissing. You hear them stop for a moment and panting

Book: I'm sorry for how I treated you back in BFB, Taco.....

Taco: It's okay, Book.... I love you now anyway...

Book: Me too..

You hear the two go back to kissing
