"Knock Knock ..." Doctor Catherine knocked on a door at the end of the hall. 

"Yes, please come in" said a man from behind the door. The door slid open automatically. Doctor Catherine came into the room and was followed by Doctor Richard who came into the room. The interior in the room is completely white. There is a long table and several chairs that are also white in the middle of the room.

"Good afternoon Professor" said Doctor Catherine. A man sitting behind his desk looked directly at Doctor Catherine.

"Good afternoon Doc. How? Have you met him?" asked the man with glasses and thin hair.

"Already Professor. Does Professor Alex have time to talk to us now?" 

“Let's talk now. So how? Is he what we thought he was?" asked Professor Alex, removing his glasses and placing them on his desk.

"Yes Professor. I've met him earlier and he does have a special ability. On his body, there were no scratches or bites from the zombies. His vitals are all normal. He just looks a little limp”

“Hmm. Okay, I'll see him today" said Professor Alex as he approached Doctor Catherine and Doctor Richard.

"Professor, is that tool you are creating now able to function one hundred percent safe?" asked Doctor Richard, who was sitting in a white chair.

“Hmm, if you say one hundred percent safe, of course not. But we don't have much choice. If he is what we expect, we must carry out this project as soon as possible. You know, the virus spreads very fast and we are running out of time” replied Professor Alex with a serious expression.

"Yes, what you said is true Professor. We don't have much choice. Okay then, we'll go first. Just let me know if you want to see her, ”said Doctor Catherine.

"Okay then. Hopefully he is what we have been looking for” said Professor Alex. Doctor Catherine only smiled faintly and immediately left Professor Alex's study.

"Hmm this is very good ..." said Eren while putting a spoonful of warm porridge into his mouth. He felt it had been a long time since he had tasted such delicious food.

“Where am I actually? And why do they know my name?" muttered Eren questioningly to himself. Because his body was still weak, without him knowing it, Eren fell back asleep on the bed.

Several hours later ...

While Eren was resting, suddenly Professor Alex, accompanied by Doctor Catherine and Doctor Richard, came back to the room where Eren was being treated.

"Good evening Eren. I am Professor Alex” said Professor Alex while holding out his hand to Eren. Eren who just woke up from sleep shook Professor Alex's hand slowly.

"How do you feel now Eren?" asked Professor Alex after releasing his hand from Eren's.

"O, good Professor ..." Eren replied briefly. From the look on his face, it was clear that Eren was still a little confused by what had happened. He also still did not fully trust Professor Alex and the two doctors who accompanied him.

"Eren, can you walk? Will you take a walk with me?" asked Professor Alex with a faint smile. Eren didn't answer Professor Alex's invitation, he just lowered his head.

"Why Eren? I know you must still be confused by everything that happened. Later I will explain everything to you. But now come with me for a walk in the back garden, ”said Professor Alex to persuade Eren. Eren thought for a moment and finally he got out of bed.

"Let's go for a walk ..." said Eren, staring at Professor Alex's face. A smile immediately spread across Professor Alex's face, when he found out that Eren wanted to be invited to go out with him.

"Professor Alex, we'll stay with you two," said Doctor Catherine.

"No need. The two of us are enough. I'll let you know later ..." said Professor Alex as he stepped toward the exit of the room where Eren was being treated. Doctor Catherine and Doctor Richard could only accept the decision from Professor Alex.

 “Thank you Eren, you already want to go out with me. I know you have a lot of questions in your head. Why is this, why is that. Right, Eren?" asked Professor Alex as he walked towards a park at the back of the building. Eren also walked side by side together with Professor Alex.

After a few steps, they came to a garden at the back of the building. With lush trees towering high and green grass spread out around the garden, coupled with the sound of birds singing from various angles, spoil the eyes and ears of anyone who comes to that place. Several people were seen lounging in the garden area.

“This place is so beautiful” said Eren with awe. Professor Alex smiled again at Eren's words.

"You haven't seen a scene like this in a long time, huh?" asked Professor Alex, looking at Eren's face who was still in awe of the beauty of the garden.

"Yes Professor. I haven't seen this soothing sight in a very long time. This is like a dream for me" 

"Let's sit there ..." said Professor Alex, pointing to a garden chair made of wood not far from them. Eren also followed Professor Alex's invitation, the two of them immediately walked towards the garden chair.

"Ahh, it's so calming in here" said Eren as soon as he sat on the park bench.

"Are you happy with an atmosphere like this, Eren?" asked Professor Alex, staring at Eren's smiling face. Eren nodded his head slowly.

"Now if you want to stay in this atmosphere continuously, you have to do something for me" said Professor Alex in a serious tone.

"What did it do?" asked Eren curiously.

“I want you to do a mission. This mission is very important for human survival” replied Professor Alex. Hearing Professor Alex's answer, made Eren's face, which was originally relaxed, become a little tense.

"For human survival? What do you mean, Professor?" asked Eren with a confused face.

“Hmm… So this is it Eren. You know what the state of our world is like right now. Everything's messed up ... " 

"Yes, I know Professor. This is all because of the 'S' virus, right?" asked Eren confirmed.

"Yes, that's right Eren, all because of the 'S' virus. Just so you know Eren, every effort from both the government and the world to prevent the spread of this virus has been done, but it seems all in vain. The virus spreads so quickly that the world has become like this” said Professor Alex while slightly lowering his face.

"So what mission should I undertake Professor?" asked Eren again.

“Your mission is very important Eren. You have to go back to the past” replied Professor Alex while glaring at Eren's face.

"What? Back to the past?!" Eren was so surprised to hear the answer from Professor Alex.
