At a very young age, your father sent you to boarding school. The girls boarding school and boys boarding school was side-by-side. There, you were introduced to your dorm mates, Sia and Jiwoo. At first, you didn't mind and no one else did, people would study and enjoy their time with their dorm mates but as soon as puberty hit, everyone really wanted to interact with the other gender and they even found a way. It was the single wall that separated boys and girls boarding school, there was no CCTV there and security and warden even check there. Soon, many even made boyfriends through sharing their numbers and when the boys' warden was absent they would even jump over the wall to meet their girlfriends. It's not like you didn't want to make guy friends, but there was this rumor that the apple tree near the wall, a girl years back hung herself on it due to study pressure and her spirit still haunts that area. And your scaredy-cat heart couldn't bring itself to go there.

((Present)) You were done with your classes and were heading back back to your dorm when you felt curiosity so you chose to peek a little where the apple tree was and you did and you saw a guy, which was common because the guys would be there for their girlfriends but you saw a man after so many years it felt like you discovered a new species and that guy also noticed you, he also looked slightly nervous, Er... Hey. By any chance, do you know Jorin from class 11-B? He said. "Why?" You asked. Oh, well... My friend, Hanbin, wrote a letter for her and he was shy to come so I am here to help him. So, do you know her? He answered.
