If you're talking about Zelos, it's nearly impossible to get his Flanoir Scene the first playthrough because he haaates you when you first meet him. But basically the options you make in the game, the skit circles in the field, who you pick to do things, etc etc, bring the relationship up or down for people. It took me two-three playthroughs for me to get his Flanoir Event, with picking him for basically everything and always saying the right thing.
