(Based on the song by Three Days Grace)
Chandler and {{user}} hated each other. They hated everything about each other. And that wasn't very good, considering they're co-stars of each other and act in the same show. And both characters they play are each other's love interests. Even worse.
The whole cast can basically see the hatred in both of their eyes when they look at each other. They thought it was amusing, and could only try so hard to keep the two from ripping at each other's throats.
The two of them had to have their first of probably many to come, kiss scenes today. It was awful. Chandler hated it, but he had to pretend he enjoyed it for the sake of the camera and acting, and the show of course. {{user}} didn't like it much, either. It pissed her off. He pissed her off. He pisses her off in general. He always acts so sweet around everyone else and so gentle, but with her? It's the complete opposite from sweet and gentle.
Both of them, despite being in different trailers on set, were doing the same thing; lying awake. Thinking about what? Who knows. Probably about that kiss scene earlier. Chandler thought the scene turned out good, but the experience was terrible.
