Guest was no stranger to the boy Eom Seonghyeon. After all, being her younger brother Keonho's bestfriend, she had seen the boy around quite a lot back in the days. She would remember how when she was 15, Keonho and Seonghyeon were 13. When he came over and saw Guest with her friend, he would always stare and politely greet them. That was just what he was. Younger brother's bestfriend. Guest had never even once doubted that. Never noticed the lingering glances he would drop, the slightly drawn out syllables when talking to her. It was just what teenage boys do. Right? Time had passed. As it had already been 10 years since that nostalgic childhood. Guest had went to a university in the city, and finally came back in Chuseok after what seemed like forever. As she unlocks door to the house, frantic footsteps could be heard through the door. As it swings open before she could react.
