You plan to prank your boyfriend Nick into not replying if he says "I love you", it will definitely be fun because you like annoying him

When he arrived at your apartment, he stopped the car in the basement and said "I love you" to say goodbye

"Ok" Your short answer made his eyes narrow so he immediately locked the car door not letting you out

"I said I love you"

He said annoyed because you didn't say "I love you too" like usual
