It was a minor argument. The few words exchanged in the heat of the moment cut deeper than expected, and the sound of the front door closing instantly chilled the air in the house. Jeon Suhyun left without a word, and you, left behind, spent the time aimlessly fiddling with your phone. No message came. At first, you thought he'd be back soon. You expected that after two or three hours, he would open the door as if nothing had happened and offer a brief apology. But evening passed and night deepened, yet there was no sign of him.

To forget your anxiety, you mindlessly opened social media.

Your fingers scrolled through the screen out of habit, letting meaningless posts flow by. Then, a stranger's account caught your eye. At first, you clicked the photo without thinking. But in the next moment, your heart sank.

Jeon Suhyun was in the photo. Familiar clothes, a familiar smile, and a relaxed expression he rarely showed even to you. He was acting all lovey-dovey with that woman, and in another photo, they were holding their faces close together, playfully making heart poses. The last photo showed them sitting across from each other by a cafe window, looking at each other and laughing. To anyone's eyes, they looked like a sweet couple.

Your fingertips trembled, making it impossible to swipe the screen. Below the post was a short sentence, 'Happy today too,' with a heart emoji, and the comments were full of people saying how well they suited each other. You felt suffocated. Not wanting to believe it, you checked when the photo was posted. A few hours ago. It was the very day he had fought with you and left the house.

Your chest tightened. With the last hope that it might be an old photo, you even checked his account, but there were traces of them posting photos taken at the same location on their respective stories. The timing overlapped perfectly. Your strength drained away so much that the phone almost slipped from your hand.

The living room was quiet. Only the ticking of the wall clock echoed regularly, and the dinner that hadn't cooled down yet remained on the table. The food you hadn't even reheated so you could eat together when he returned had long since hardened cold. You turned your phone on and off repeatedly, just staring at his profile picture. Should you call him, confront him, or just say nothing? You agonized over it countless times but ultimately couldn't do anything.

Time passed cruelly slow. Midnight passed and it became one in the morning, but the front door did not open. Only the faint sound of passing cars could be heard from outside the window. Sitting on the sofa, you stared blankly at the entrance, only to find yourself looking at that photo on the phone screen again. The face of the smiling Jeon Suhyun was so natural. It was hard to believe it was the expression of someone who had just fought with you.
