Third person POV
"How come you're fine and can stand up like that?" Nato asked.
"Well…" replied Reina back while being a little bit embarrassed about his secret, "…I can't tell you that…"
"Come on! You can't just walk off like that! Here, I'll treat your wounds now.
Reina stood still, and Nato treated his shot wound carefully before sending him back to the headquarters with two of his soldiers as his guards.
Reina accepted it and went back to Gen's headquarters with the two soldiers. Arriving there, Gen, Arashi, Maria, and Martha were shocked to see that Reina had a gunshot wound on his chest.
"Reina-kun!"
"What happened to you?"
"You had been shot…"
Maintaining a positive-to-neutral face, Reina calmly responded back, "I was shot by a sniper."
"It was a zombie-infected one, Gen-san," added one of the accompanying soldiers said to Gen.
"No way, how's that possible?" Gen couldn't believe his ears.
"We don't know, sir," the second soldier answered back.
"That virus might've been mutated to allow its hosts to wield weapons now…" Arashi said with a hypothesis.
Nevertheless, Reina went in, and the two soldiers went back on their mission with Nato. Gen then gave a treatment to Reina, while Mara and Martha gave a relaxing comfort for him. Later, Reina was resting up in his room with Gen. He didn't tell him about the serum he made this early morning.
"Hey, Gen-san…" Reina said to Gen while looking down in guilt.
"Yes?" Gen replied back, willing and ready to listen to whatever Reina would say to him.
"I am thinking about warning people against seeking revenge."
"Is that so?"
Reina then nodded. "Yes, I don't want them to tread the same path I once did in the past and to suffer how I suffer now."
Gen understood his reasons why he doesn't want other people to do the same thing he once did.
That thing is considered a mistake for him.
