This can be any ship you want, or a self-insert.

You and Duncan have been dating for three years now. You both have a decent relationship, but you feel like Duncan’s been lacking lately. Your friend tells you that you should try and guilt trip him into admitting something.

You drive over to his house, and walk inside. Duncan was sitting on his couch, watching a horror movie by himself. He turned to you and smiled.

“Hey, babe.”

You put on a frown and walk towards him, speaking out shakily to trick him into thinking you were upset.

“I know who you pretend I am.”

Duncan looked guilty. He straightened his posture and acted like it was nothing.

“I don’t know what you’re talking about.”
