You were a famous YouTuber, known mainly for prank videos on friends, with some vlogs mixed in. One night at a bar, fate intervened - you met Gyeong-su, your now boyfriend of three years. You hit it off instantly, exchanging socials and quickly setting up a date. You still remember how nervous you were, putting on your best cologne and cleanest button-up shirt.

That day remains one of your best memories. After about a year of dating, you moved in together, and eventually you started focusing your pranks on Gyeong-su. He knew about your YouTube career and never minded the little pranks you'd pull. Plus, he saw most of them coming anyway, always reacting with feigned surprise because he knew it made you happy.

You saw a TikTok video of a fake hickey prank and immediately decided it would be your next project. You called a friend to help you create the fake mark while Gyeong-su was out grocery shopping. Perfect timing. Your friend arrived with makeup supplies and helped you apply the realistic-looking hickey - you were hopeless with makeup yourself. When finished, you were amazed at how real it looked. You thanked your friend profusely before she left, then prepared everything for the prank.

You ensured your camera was fully charged and hidden discreetly - barely visible unless someone knew where to look. Then you put on a hoodie to cover the mark. Soon, Gyeong-su returned from grocery shopping, and your heart raced with anticipation. You took a deep breath, turned on the camera, and went to help him carry in the groceries.

You were nervous he might see the hickey before you reached the couch, since there was no camera in the kitchen. You carefully positioned yourself so the marked side faced away from him. Once you finished putting away groceries, you suggested cuddling on the couch to watch a movie. He agreed happily, looking slightly tired.

As you settled on the couch, you subtly pulled your hoodie down so the top of the mark peeked out. You chose a movie and started watching. About 15 minutes in, he looked up to press a kiss to your jaw when he noticed the hickey. You felt his breath hitch and his body tense. You looked down at him and asked what was wrong.

He roughly shoved your head aside, pulling down your hoodie to expose the purple-reddish mark on your skin. "Who did this?" he hissed, betrayal evident in his voice. He forced himself out of your grasp as you tried to play confused and deny anything was wrong. He kept pressing, eventually shoving you down onto the couch, pinning you beneath him.

"I said who did this?! I don't leave visible marks! Hell, I hardly leave marks at all! Who did this? And how could you cheat on me? After everything we've been through!" He harshly rubbed his thumb across the makeup, smearing it on your neck and his finger. He stared at the smudge in disbelief, sadness, and overwhelming frustration. He could usually predict all your pranks, but this one... You'd gone too far, and the sadness in his eyes told you everything.

He got up off you, tears streaming down his face as he marched into the bedroom and slammed the door. You heard the distinct click of the lock as you glanced at the hidden camera. You got up, turned it off, and made your way to the bedroom door. You knocked lightly, calling his name.

"Go away! I don't want to talk to you." You heard a muffled, choked sob from the other side. You knew you had to apologize for scaring him like that - you knew how fragile his emotions could be.
