She was about get the phone to call Kyouma with her hands shivering while all of a sudden, someone rang the doorbell.
She opened the door, it was Kyouma.
"K-K-Kyouma…?"
Kyouma entered without Riza's permission.
"Listen carefully. You and Roy are best of friends since college, the two of you have separated after college for 4 years, someone told you to change and you obeyed it, and you regretted it because you realized it's wrong. He asked you to marry him but he was hit by a truck."
She can't move her body as if she was paralyzed.
"H-how–" Before Riza, who's struggling to utter a word, could finish what she was about to say, Kyouma interrupted.
" 'How come you knew all of these? Tell me… TELL ME!' were the words that you're about to say, Riza."
Now, she really wasn't moving as if her heart stopped beating. She didn't know if she will feel astonished, shocked or petrified.
"In the Beta world, there was no man who said 'that' lines. You didn't force yourself to change. You and Roy still met at 'that' TV store, and the two of you still confessed your love. Roy still asked you to marry him, and you said a 'yes'. There was no truck so, he didn't die. At that day, you called Kurisu and you told her that you and Roy are engaged. Kurisu and I were at the same place so I heard you. We congratulated you, though we didn't know you had a boyfriend. At the wedding day, Kurisu tried to attend even though she already told you that she couldn't come. Unfortunately, she was hit by a car and DIED."
"W-W-What did y-you just s-s-say?"
Roy didn't die. Our marriage wasn't postponed. There was no truck. Roy didn't die. I called Kurisu to tell the good news. I was congratulated. Roy didn't die. Roy didn't die. Roy didn't die. KURISU WAS HIT BY A CAR AND DIED. Roy didn't die but KURISU DID.
Kyouma, despite of being a man, didn't hesitate to cry in front of her.
"T-that's why… I-I used the Time Machine that Kurisu made to go to the Alpha World, h-hoping that in this world… she won't die."
Riza suddenly had the strength to react.
"Do you know…how it hurts… to see your love DIE in front of you…while people were just watching you CRY YOUR EYES OUT?!" Why are you so selfish, Kyouma…? Why?! Is this the only way to save Kurisu?! Why did you let Roy DIE, WHY?!" Riza cried out while grabbing the collar of Kyouma's lab coat.
"It was the 15th time you told me that. I had time leapt for 30times, finding an alternative way to save Kurisu. My 1st attempt, she was stabbed and died. My 2nd attempt, she was shot and died. My 3rd attempt, she was kidnapped and was killed. 4th attempt, she was food-poisoned and still died. Now, you're telling me that I'm selfish? Yes, I am. I REALLY am! I have told you this line for so many times and I will never get tired of it! If I am really selfish, tell me…do you know… how hard it is… to see your love… DIE IN FRONT OF YOU… for SO MANY TIMES?!" Kyouma exclaimed.
Riza prevented herself to reason out because she realized what Kyouma had gone through was harder than she experienced.
