Kazuya, do you remember the first time we met? You who refuse to shout out a word of pain even though your whole body hurts to death; you who obviously don't want to lose but have to admit defeat; you who obviously want to teach others but pretend to be a cold senior; you who are obviously not used to it but don't want to trouble others. Everyone is you that I love, but why can't you be with me? Why do you have to forget me in the end? Kazuya, will you remember that we once loved? Will you remember that I used to work so hard to love you? Perhaps the best outcome is if you all forget me, isn't it? This is the meaning of my existence, just like a passerby. Who am I? The first meeting you have in your mind is actually a premeditation. You died with regrets in your previous life. If you meet me in this life, then who am I? Judging from his actions, he and I are not the same people as you in this world.
