"Jungkook, I think we'll have to move because of mom and dad's company."
"Yes..? Where to...?"
"I think I need to move to a new area."
"Yes..?! Uh, that won't work..."
"I'm sorry, but I couldn't help it."
"I've already seen the house, so Jungkook just needs to go."
"Jungkook, your mom will pack all your stuff for you, so go say goodbye to your friends tomorrow, okay? Tomorrow is your last day."
"....It won't work...."
Jungkook couldn't bring himself to say hello to Yeoju. So, after telling Yeoju's parents, he moved away. That's how I was separated from my sister. We became so distant that we couldn't even contact each other.
At that time, my goal was only one thing: to grow tall quickly, meet my sister again, confess my feelings, and return to where she lived.
And then, suddenly, starting in middle school, I started growing taller. Then, in my third year of middle school, I took the bus and subway alone and ran to the rooftop I'd always gone to with my older sister. Because I played there with her every day, I have the most memories with her, and I had a feeling she'd be there.
As I approached the rooftop, I heard my sister's voice, and a long-awaited happiness surged through me. I opened the rooftop door, and sure enough, my sister was sitting there.
My sister was sitting with her back to the door.I was so happy to see my sister that I slowly walked forward and tried to call her, but she was with another man.

I just froze in place.
"Hey, Kim Seokjin! What are you doing! I was surprised... Why are you suddenly pushing me?"
"ㅋㅋㅋ That's why I was holding your hand~"

(Hold my hand..?)
At that time, the man was holding my sister's hand as if they were lovers.
So I thought they were dating.
And the way they looked at each other looked so happy.
"Oh, I told you my secret place and you're just kidding...!"
Seokjin said while stroking Yeoju's head.

"Okay, I'm sorry."
Jeongguk couldn't bear to watch that scene any longer. He felt like he was about to explode with anger or jealousy.
So I went down to the rooftop right away, and for a year after that, I didn't go back to that rooftop or to Yeoju's house.
After a year had passed, Jeongguk, who was now a high school freshman, moved back to his old neighborhood, saying he wanted to live alone, and also transferred to a high school near his house.
When I returned to the neighborhood where I used to live, I wanted to see my sister again, so I went to her house five times a day. But... I was afraid that I would see something I didn't want to see, not something I wanted to see, so I only went to her house when she wasn't home.
Things that would become my second most memorable experience at my new school began.
High school was fun. I made good friends, so school life was easy. Occasionally, I'd think of my older sister, but I just let it go.
When I was in elementary and middle school, my life was filled with thoughts only about my older sister, but now that I was in high school, I had good friends in my life, and unlike in the past when I was sure that I would never meet anyone but my older sister, I also had a kind, pretty, and lovely girlfriend. At the same time, I thought that my older sister was just an ordinary first love that I would eventually forget. But in the end, I just couldn't forget my older sister.
Now that I think about it, I think I met that other guy just to forget you. I didn't meet him just to forget you. I really, truly liked and loved him too, but it was you that made me like him, because I kept seeing you... I only realized that a few years after we started dating. But once I found out... I couldn't do anything to him... I felt sorry... I was so sorry... I couldn't do anything... And that's how we broke up. I thought breaking up was the right thing to do. I wanted to go back to being friends, I didn't want to lose him as a friend, and I was greedy to hold on to him.
So after that, I went to the rooftop with Suji once or twice a week... no, I went to the rooftop with my older sister every single day, like I was attending class every single day. And during my freshman year of college, I heard a few rumors about my older sister. That there was an incredibly pretty goddess in my second year, but I wasn't interested. I didn't know it was my older sister. And so another year passed.
After that, at the MT I went to because of Park Jimin a while ago, I got annoyed by someone who kept staring at me, so I went to that person. At first, I didn't recognize them. But the moment I heard their voice, I knew right away that it was my sister. When I looked again, I saw my sister's face, which I hadn't recognized before, when she was younger. I was so happy, but I also hated it. It was annoying. She was my sister whom I really wanted to see back then, but I hated seeing her so much. So, whenever my sister talked to me or approached me, I wanted to put up a wall around her and make her feel bad too... But... It was that person again... Why is this person still by my side? Why is he always so friendly with me? It's annoying... So... my wall... the wall I had built around my sister... crumbled... because of that person... No... to be exact, not because of that person, but because of the anxiety I felt again at the thought that my sister might like that person... It crumbled.
