I remembered that Jinsol saw everything that happened that night and went to tell Songyeon. I remembered that I walked to your dorm with tears streaming down my face as I held the emergency spare key you gave me. I remembered that I walked into your dorm, and Younghee saw me. She asked me what was wrong, and I just told her that you forgot everything. I told her that your memory reseted. Baby, do you know what she told me?
She told me to go back to you. She told me that, what if you remembered everything again. She told me that you'd be heartbroken when you finally remember me and found out that we broke up during that night. Even I couldn't believe what I told her next.
"It's what she wanted. Take care of her. Goodbye."
As I said that, I took the notebook full of our memories, left the spare key on your bedside table, and walked out of the room.
