I felt a pang of guilt as I looked down at the notebook in my hands. I knew it was rude of me to have looked through it, but I couldn't help myself. It was as if the pages were calling out to me, begging me to explore their secrets.

As I flipped through the pages, I felt like I was invading your privacy. I saw your thoughts and ideas laid bare on the page, and I couldn't help but feel like I was intruding on something that was meant to be private.

The voice of reason in the back of my head told me that I needed to look through the notebook if I wanted to return it to you. I couldn't just leave it lying around. I needed to find a way to get it back to you.

However, guilt consumed me, and with a heavy heart, I placed the red notebook on my desk and turned off the lamp. The room was plunged into darkness. I tried to go to sleep, but I could still feel the weight of what I had done.

I lay in bed, staring at the plastic glow-in-the-dark stars on my ceiling. I couldn't help but think about the notebook. I thought about the kind of person you were, and I couldn't help but feel like I had a connection to you. There was something about your writing that spoke to me, and I knew that I wanted to get to know you better.

[KIM SEOKJIN'S LETTERS]

Dear Nari,

As I sit here and reflect on the moments we've shared, I can't help but be overwhelmed by the depth of emotions that have blossomed within me since our first meeting. From that very instant, a special place was carved in my heart, reserved solely for you.

From your love, Seokjin.
