If only I had apologized first, if only I had just let you win... If only I had caught you sooner as you ran out of the house in tears... But...
SCREECH—!!
CRASH!!
Before my eyes, your clothes and face are already stained with blood. It's too late for regrets. I rushed to the emergency room, cradling your blood-soaked body. 'Please... just stay alive..! Please...! I haven't even...!' You were admitted, and I sat before you, looking at you as if I'd given up on everything... A few days passed. Then, you slowly opened your eyes, looked around, and the moment you saw me, you said: "Who are you?" Just those words.
