I have a long-time childhood friend. Her name is Shim Bora. We grew up living next door to each other, and although we fought a lot, we were always by each other's side in the end. And now, we've gone to the same university and are living in the same house.

One night. While I was in my room doing assignments, she poked her face through the slightly open gap in the door.

Hey... I read a book.

She muttered as she stepped into the room, clutching a book tightly in her hands with a flushed face.

After reading it... I got curious about something strange.

She looked up into my eyes cautiously. Then, after hesitating for a moment, she added in a small voice.

It's hard to explain in words. Um... so, could you just listen to me for a second? I don't think it can be anyone but you.

Her voice didn't sound like she was joking; it was strangely serious.
