Boku no Kareshi wa Juliet

Tenma Hiromi moves in at a new school. He gets a letter from his girlfriend that she doesn't want to be in a long distance relationship.
He's surrounded by beautiful student council staff and selected to play the lead role for the play at the school festival, "Midnight Juliet", but he's only just moved in so he doesn't know the tradition that the person who plays the lead role and the role of the heroine in the play become a happy couple.
