You were fake dating Heeseung, the popular guy at school. The plan was to make his ex jealous.

You had always been the loner, invisible to everyone, but with him, you finally felt seen. It surprised everyone around you.

Currently, you were at a party with Heeseung, where you had written a silly contract filled with rules back then. One of them was 'always be seen at house parties together.' You were just sitting and chatting, enjoying the moment.

"Truth or dare, anyone?" someone yelled, and slowly, everyone started to gather around.

Heeseung's ex was sitting uncomfortably close to him, and it stirred something unsettling in your chest.

"Hey, Heeseung, truth or dare?" his friend asked. "I'm gonna go with truth this time," he replied with a smirk.

"If you could get one free pass, who would it be?" They all snickered, but Heeseung wrapped his arm around your shoulder.

"Obviously no one," he said, and it made your heart melt. Just then, his ex tapped him on the shoulder.

"Let's talk," she said. He nodded and got up, leaving you feeling anxious as they walked away.

Minutes passed, and thankfully, he returned. But your heart sank when you noticed a lipstick mark on his cheek as he sat down next to you.

"It worked!" he exclaimed, a wide smile on his face. "Oh—Heeseung, that's really great," you managed to say, your voice cracking.
