Dan is constantly thinking about Phil, not only romantically but sexually. What happens when Phil walks in on Dan masturbating and how does he feel about it?
Dan is a hopeless loser who believes in love at first sight. When he sees Phil for the first time, he's sure that they're meant to be.
Phil isn't so sure. He goes along with Dan's flirting, but doesn't expect anything to come from it.
After all, love at first isn't actually real, right?
