Arin finds him alone in the locker room with lights off, while everyone is busy doing their chores. No one but inside that dark stuffy room, in front of his small mirror attached on his locker door, is the guy who seems to be talking to someone else. Strangely, he isn't on his phone, but straightly to his reflection in the mirror. ‘You’ll never win. You think you’re strong now?’ she hears him say. In his mirror, shows a reflection of someone who’s afraid, a frightened face of Oh Sehun. ‘Hyung, stop this. Leave me alone!’ he says to his reflection. That frightened face suddenly turns into an angry version of him. ‘Stop calling me hyung! I’m not your brother. I am Oh Sehun. I am the only Oh Sehun. Your brother is long gone!!!’ Once in a while, the angry face turns into a frightened face. But he’s only referring to the mirror, pointing out his own reflection. Arin can’t understand what is happening to her friend. She braces herself up and eavesdrops to Sehun's company. She might have missed some of the ‘conversation’. but what she hears next is him yelling, ‘LIAR!!!’ Oh Sehun forcefully slams the locker door, locks it and rushed out of the room with his shoulders down his knees. Good thing, before he could even open the door, Arin already left. -- ‘Sehun-ah, we’re friends right? Never forget I’m always here to hear your side.’ Arin suggests when she’s with him again at the dishwashing area. Sehun smiled at her, ‘Don’t worry, I’m alright.’ ‘So, would it be okay if we eat some noodles tonight? The noodle house in our village offers very delicious jjajangmyeon. I bet you’ll love it.’ They both go to the noodle house then ordered their meals. ‘Sehun-ah, how is it?’ ‘Thanks for bringing me here. It’s my first time eating this one of a kind jjajangmyeon!’ he said and a gulped the glass of water next to his bowl of soup. Arin, who is watching him eat, imagines the other Oh Sehun who was complaining about the dark lipstick. She can also remember the way he wiped the lipstick off that guy’s lips. She is snapped back to reality when she finally hears Oh Sehun calling her for the third time now. After their noodle treat, Oh Sehun walked her home and waits until Arin disappears inside the building. Arin who had fun with him, is somewhat disappointed for not seeing the red sports car in front of her building tonight. He’s just busy in the bar, right? -- It is another night and Arin is expecting his red sports car outside again but there was nothing except the emptiness of that small parking area where he used to stop until Arin shows up. Arin can somehow feel the emptiness without seeing him in a day, but she still won’t admit it’s the terms ‘she’s missing him.’ When she’s already taking a nap at the corner of the stairs at the building entrance, she hears her name being called and her smile could’ve appeared until she sees it’s the other Oh Sehun. He brought some drinks and snacks with him. Well at least, he’s still a friend. But for her, no one of them is a replacement. They’re both different and so do her feelings for the two of them. Still, in her mind, that Oh Jihoon’s identity and that moment she caught this guy talking to himself in front of the mirror is still a bugging her. She has a lot of issues unresolved and she has to find these out. -- Her phone rang just as she finishes brushing her teeth. It’s another weekend and his friend, Oh Sehun calls her to go watch a movie. She agreed to go and still expecting that for some time today, that bar manager would pass by. Oh Sehun grabs her hand and they ran when the movie’s about to start. The way this Sehun held her hands, Arin would remember how the other Sehun grabbed her for the first time at the disco bar, when she first met him. It’s already late and they’re still on their way home, on the bus. Arin fell asleep and she must’ve been so tired. Sehun watches her sleep peacefully leaning on his shoulder. He knows Arin wouldn’t know since she’s asleep so he slowly inches near her and places a peck on her lips. Arin was awaken by his kiss and catches him getting away with it, acting completely awkward. Arin didn’t say a word to him even until they boarded off the bus. When they’re already walking by the street, Arin is walking before him. Arin just can't understand how could he steal a kiss from her at the moment of her off-guarded unconsciousness. ‘Arin-ah, I’m sorry about---’ ‘I'm going home. You should go home too.' She just said and continued walking. -- The strangeness of the night creeps her out and shivers with idea she is being followed. She knows a car is moving slowly behind her, a black car she noticed when she had a chance to take a glance. She can't glance back again and just she continued walking as if nothing's wrong. All she could do is to walk faster than usual but the more she speeds up, that car behind unstoppably follows her. 'Am I really being followed? Am I going to be kidnapped? What should I do?' she asks herself. Although she's nervous, and even more as she reaches the intersection and takes turn to another street, where that car is still following her. She finally got pissed and yells as if the driver would hear her, 'YAH~! Why do you keep following me!' and just as she said that, the black car's headlight made her cover her eyes with her hand. As the light disappears, someone's coming out of the car and it's Oh Sehun. It's him...again. 'Yah! Was it you all along?' she asked. Oh Sehun chuckled until Arin kicks his leg. 'Why, were you scared?' Arin just frowned at him and continued walking, still couldn't believe it was him after all. She then turned back, 'I don't trust black cars, you know.' Sehun drove his car again and followed her and as he reaches her, 'Hey, don't you think it's creepy? It's too dark on your way ahead, I can give you a ride!?' Arin stopped her pace and opened the door of the car. On the way, Arin suddenly spoke not knowing her intentions at all. 'I didn't see you for a while, huh.' Sehun's grip on the steering wheel suddenly got tighter, hinting something strange on Arin's statement. Still managing to focus on the street, he asks, 'Why, did you miss me?' 'Are you crazy?' A
