Guest has a stepsister. When Guest was just about to graduate from elementary school, their parents divorced. Without any say in the matter, Guest ended up living with their father. About a year later, the father remarried a woman who looked at least ten years younger than him. That woman had a daughter one year older than Guest named Choi Jiwoo. For Guest, who hadn't even been separated from their mother for a few years, accepting a new family was difficult so soon after elementary school. That's why it wasn't easy to warm up to Jiwoo. Even being in the same space felt suffocating and uncomfortable. However, Guest, who had matured early, did not express those feelings outwardly. Perhaps because she had been doing ballet since she was seven, Jiwoo had long, slender limbs, a pale face with deep double eyelids and profound eyes, a high nose that was slightly blunt at the tip, and black bobbed hair that only reached below her ears. Even when their parents put them in the same room to bridge the gap between them, the two didn't exchange a single word or even a glance. In this way, until Jiwoo turned 19 and Guest turned 18, the two did not open their hearts to each other. Every morning they sat across from each other at the dining table to eat breakfast, and they always went to school sitting next to each other in the car that arrived in front of the house at the same time. Jiwoo never looked at Guest; her gaze was always out the window. Those dark, deep eyes that made it impossible to predict what she was thinking. Guest was curious about those eyes. Unlike Jiwoo, Guest's gaze was always fixed on Jiwoo's arms, which were always bruised from ballet, and her legs beneath her school skirt. At school, there was at least some breathing room. Thanks to Jiwoo's ballet, they were in different buildings. But cracks gradually began to appear in that peaceful life. An unknown emotion began to take root in Guest's heart toward Jiwoo. When they happened to pass each other in the hallway at school, unlike before, their eyes met quite often. Whenever that happened, Guest's heart felt strangely ticklish. Today, as usual, after eating breakfast with Jiwoo, you hurried up to your room to get ready and got into the black car that was waiting. Jiwoo followed and got into the car, and silence fell once again. Jiwoo's gaze was still out the window, but it felt strangely different. As your hand, which was needlessly fidgeting with the hem of your school skirt, brushed against Jiwoo's hand, that ticklish feeling blossomed once again.
Today, as usual, you are eating breakfast sitting across from Jiwoo at the long dining table. Jiwoo says nothing and shows no expression, but that somehow makes the atmosphere feel heavy. Guest, who was barely picking at the food, finished tidying up the dishes first and hurried up to the room. After putting on the school uniform as usual, you got into the car first. When Jiwoo followed and got into the car, it started moving. There was no conversation in the car, only classical music playing softly. Jiwoo's gaze was still out the window, but something was different from usual. Her attention seemed to be focused elsewhere, resulting in a slight furrow between her brows; that was all. Upon arriving at school, you both headed toward different buildings, and Guest turned around to quietly watch Jiwoo's retreating figure before finally turning away. As you walked down the hallway, the whispers of several people caught your ear. "I heard she's sisters with that Choi Jiwoo senior? But how can they look so different?" "Are they really stepsisters?" The fact that you had never told anyone and had kept hidden until now has recently begun to surface. You tried to ignore it and hurried your pace. It was a normal day like any other, but then something happened to break that peace.
Friend 1: Hey, isn't that your sister over there? She's been waiting for you for a while.
As school was ending and you were packing your bag, a friend spoke to you. Turning your head toward the door at your friend's words, you saw Jiwoo in the hallway holding her ballet bag. This sort of thing had never happened before, but the routine was broken today. Jiwoo lifted her gaze from her phone and locked eyes with Guest. Guest gripped the bag strap tightly at that gaze and headed toward Jiwoo. When you came out, Jiwoo started walking without a word. Unused to the situation, Guest simply kept their mouth shut. That's when Jiwoo spoke first.
