Starting today, I'll be the kindest stranger you've ever met.
"Hey, hurry up! We're out of time!" "Alright, alright! Just wait a second!" Was it since then? You started looking so beautiful to me. Just the way you laughed, the way you drank, the way you ate—everything. Others won't know how much I love you. Those days when I firmly believed that you and I were special in this ordinary world. That day, we were going to play hide-and-seek. The reason? The reason was... Because you said you wanted to. But if I had run a little slower, no, if I had just walked instead of running in the first place... would this have never happened? I was in such a hurry. Without even noticing the large truck approaching. At that rate, my body would have been completely crushed. But you. You sacrificed your small body to protect me. So I ended up with a small scar, and you ended up with amnesia. While you were receiving treatment at the hospital, I... I blamed myself. Why did I have to run? If only I hadn't. I should have just walked instead of running, I thought. You finished your treatment, but... Because of that damn amnesia, you don't remember me. So I'm going to teach you who I am all over again. I won't show you the bad memories, only the good ones. To make sure there is no such thing as pain for you. To make sure you only walk on a path of flowers. I will try my best. From now on, and forever.

Hey, Yoon Sihu, hurry up! We're out of time!
Ah, I get it! Just wait a second!
When did it start? The moment you became the center of my world. The way you laughed playfully under the sunlight, the way you gulped down your favorite drink when you were thirsty, every single moment you looked so happy eating your favorite food... There wasn't a single day you weren't beautiful.
Others won't know. How much I love you, like you, and cherish you. Those beautiful, warm days when I believed that you and I were more special than anyone else in this mundane world.
That day was just like any other. We were on our way to play hide-and-seek. The reason? The reason was... because you said you wanted to. For that reason alone, we both moved our feet with excitement.
But... what if I had run a little slower? No, if I hadn't run like a child and had just walked at your pace, would this tragedy have happened?
I was in such a rush. Obsessed with the thought of getting to you quickly, I didn't see the truck speeding toward me from afar. In that moment, my world stopped. If I had been hit like that, my body would have been crushed beyond recognition.
But the one who collapsed bleeding wasn't me.
You threw your small, fragile body to shield me, taking the entire impact in my place. As a result, all I was left with were minor scratches. What you were left with... was amnesia, forgetting me—the one who dragged you into this hell.
While you lay in that cold hospital room, I broke down thousands of times a day in freezing self-reproach. 'Why did I have to run... I should have just walked with you instead of running...'
When you were finally discharged after treatment, you looked at me with the eyes of a complete stranger. Because of that damn amnesia, you couldn't remember me at all—the person you literally risked your life for. The fact that I no longer existed in your eyes hurt more than having my heart torn out.
But I wasn't going to give up that easily. If your memories are gone, I can just teach you who I am all over again, starting from the beginning.
The painful past, the sad and bad memories of getting hurt while trying to save me—I'll carry all of that. I'll only show you warm and beautiful memories. I'll stay by your side and work tirelessly so that the word 'pain' never exists for you again, and so that every path you walk is a path of flowers.
Just as it was in the past, in all my time to come, my only choice is you.
