A few weeks have gone by and Mikasa kept feeling the same, she didn't heal and her mother kept getting even more worried for her daughter's health. She wanted her daughter to take a break from school and try to relax, but Mikasa refused. Stating that she wanted a normal life, despite all of what has happened to her.

Mikasa called Sasha, on a rainy night and asked her how did she get to meet Jason. Sasha was reluctant to answer at first, but in the end she did.

"Uuh... it was at a party I went to. There were a lot of people I didn't know but I went with a friend at the time, and out of nowhere, he comes up to me and introduces himself."

"Is that it?" Mikasa asked.

"Yea. He seemed pretty nice and friendly. After that we happened to stumble upon each other in random places and eventually we exchanged numbers."

"You stumbled upon the same person, not once, not twice, but a couple of times." Mikasa stated.

"Yea... and we chatted and stuff like that." Sasha replied.

"And then you introduced me to him."

"... Yes..." Sasha said between seconds of silence.

"Now tell me... did he even mention where he lived?"

"Actually only once. He said he lives in an apartment a few blocks away from where I first met him, but I doubt he would have left anything there."

Sasha then told Mikasa the address and the next day they both went to the apartment.

Mikasa and Sasha arrived to the front door of the apartment building. Sasha was not feeling comfortable what's inside the building and even more uncomfortable about what Mikasa was up to. It appeared to her that Mikasa might be planning some mischief.
But in reality. Mikasa was trying to find something that will help her cure her condition.

"Hey..." Sasha said.

"Hm?"

"Once we get in, how do you expect us to, y'know... get inside the apartment?"

"Oh I have got that figured out. I have someone waiting for us up there."

"Who?"

"You'll meet him soon enough."

Mikasa and her friend both walked up the stairs of the seemingly normal apartment building and headed towards the apartment of the man who ruined Mikasa's life, Jason.

Mikasa and Sasha both arrived at the door, only to see that it has already been unlocked. Sasha hid behind Mikasa out of shock and horror.

"There's someone there!" She said.

"Of course there is! I've already told you there'd be someone there."

"Oh! Sorry. I almost forgot that while wondering why you'd bring me into the apartment of the man who drugged you, kidnapped you, tried to rape and murder you, and who's still driven by spite and bent on revenge!"

"I want to see what he could have hidden here. Possibly a clue of what the drug he used on me could be. And better yet, we could find a stash of it!"

"I think you're stretching the possibilities"

"Yea... But let's enter for now."

The two entered the apartment and saw the back of the person who unlocked the door and entered long before them.
That person turned around and revealed himself to be Connie Springer.

"Connie?!" Sasha exclaimed.

"Yes. Connie. The one and only." He replied.

"What are You doing here?!" Sasha asked.

"I'm here to help Mikasa. What about you?" He asked calmly and even with a smile.

"I'm here with her too!" Sasha said.

"I see... that you know each other..." Mikasa said while stepping away from the two to let them continue arguing.

"Yea I know him! He was the guy who broke the heart of my friend! The one I mentioned yesterday on the phone!" Sasha explained.

"Well don't get in my way before I break your neck." Connie threatened.

"Oh, you'll be the one buried six feet under!" Sasha returned the treat.

"Both of you calm down!" Mikasa jumped in.
"We're here to get some clues, not to argue."

"Okay. I've calmed down. Just tell your friend not to get in my way." Connie said as he pointed with his hand towards Sasha.

"Oh I won't. And you don't even think about getting 3 feet close to me."

"Hey!" Mikasa yelled. "Stop!"

Then all three proceeded to search the entire house for anything that might give them a clue for the drug that Jason used on Mikasa.

As they were looking, Mikasa kept getting visions of Eren and Jason. The visions containing Eren were all of a disappointed Jaeger, turning his back to Mikasa and leaving her alone.
The visions about Jason involved him trying to grab Mikasa before immediately snapping her back into reality.
Both Connie and Sasha were not there to see it as she alone was searching Jason's room.

"Oh Eren... why can't I tell you how I truly feel?" She said while being on the verge of tears.

Searching under a bed, she found a briefcase.
She opened said briefcase and was shocked to see what's inside it.
Inside were letters from Jason to someone who went by 'X'.

"X? Who's X?" Mikasa asked.

Dear X.

The drug has yielded perfect and promising results. Mikasa Ackerman is now fully influenced and obeys all of my commands. Right now it has been 3 days of her taking the drug. The only method I used was injections followed by hypnosis. I've taken advantage of all the tips you gave me. I still need more time before I could give you any official results. I haven't seen any after effects of her taking the drug. I have ordered her to not take the drug for some time. She obeyed that order and now she is unconscious on my sofa. I took her here. She does not know of this place.
Jason.
P.S: The effects were instantaneous. After the very first injection I proceeded to hypnosis and it worked like magic! She was totally under my control!

Mikasa was beyond shocked and horrified after reading the first letter. And that was only the beginning. The remaining letters were all exchanges between Jason and X talking about the drugs and it's effects on her.

She took all the letters and went outside the room after stashing the briefcase where she found it.

"Hey guys... have you found anything?" She asked.

"No. Anything on your end?" Connie asked.

"No luck. The place is empty. And even if it had anything, it would have been all gone."

"Ok. Well I'm gonna head out. Mikasa, call me if you find anything." Connie said before taking his leave.

Mikasa and Sasha followed after.
Mikasa couldn't tell them about the letters. She was too shocked about them to even mention them. She wanted to read all of them by herself when she'd return back to her house.

Later on. Mikasa took a shower and brushed her teeth. But when she took a look in the mirror, she saw Jason from the back, staring at her devilishly.
She instantly turned around, only to see that she was hallucinating.

She then shrugged it off as another vision and proceeded to her bedroom.

She looked at the letters that were scattered on her bed and started to read every individual one, starting by the second one.
All letters had their dates on them so it was easy for her to sort and order them from oldest to newest.

All of them talked about how Mikasa was reacting positively to the drug, now known as
The Pawn's Bliss.

The drug is used along with hypnosis to allow the victim to be in control of whoever drugged the individual. It was still in development and was being tested on Mikasa for a start.

Jason was working with a 'company' that develops and markets the drugs secretly without the knowledge of anyone.
How a criminal lowlife like him got in contact with the shady people he exchanged the letters with is unknown.
But she also wondered why he kept a copy of each letter he wrote himself and stashed them. As if he wanted them to be found.

The drug itself is being mass-produced in Africa and somewhere in Brazil. The exact locations are still unknown, but Mikasa had a lead on the criminals.
She didn't want to hand over the letters, as she knew that the 'X' person would find a way to avoid them, or even that the cops worked with 'X' and were on his payroll.

Jason also joked in the letters about how good Mikasa's tongue feels on his member. Suggesting that he forced her to do sexual favors for him. But he didn't go as far as taking her virginity. He wanted to leave that part out to when she outlives her usefulness. He wanted her to be conscious, afraid, and at gunpoint. Feeling all the pain and pleasure before being shot at point blank.

"Keep your cool, Mikasa. He's not gonna get you. Not now, not ever." Mikasa said to herself.

After reading through the letters, she hid them and went to sleep after locking the windows and the door.
