~Chapter 1~

                                    

                                          
Atsushi had just gotten back from work and was completely tired out. He laid down on his futon and went to sleep due to his tiredness. Currently, Kyouka was on her first big mission and could not make it home so Atsushi had the house to himself for a few days til she came back.
When he woke up he felt hot and flustered in the middle of the night. It was in the middle of winter so he did not know why he woke up like this. Atsushi felt weak, even the touch of his own clothing on his back felt heavy.
¨What the hell is happening?!¨ Atsushi said clearly unhappy about the way he feels right now.
Thoughts had rushed through his mind about what to do now, he had decided it was best to tell Yosano about this and maybe help him. He sighed and then looked at his phone to see the time.
¨Jeez, only 1:34 AM...¨ 
He laid back down in his futon trying to go back to sleep but never could due to the new heated feeling.
**A few hours later**
Atsushi got up out of his futon and decided to get ready. He had gotten no sleep at all since 1 AM. He was so ready to meet up with Yosano to know what the hell has been going on with him lately and why he was acting like this.
He got on his clothes and grabbed the things he needed before he ran off to work to see Yosano before it was too late.
**Timeskip to Atsushi arriving at the ADA**
Atsushi entered the building and walked up the stairs til he got to the door to the office. He opened the door and walked in looking around for Yosano. Til suddenly he heard a voice coming from one of the desks.
"Atsushi, you are here early...any reason why?"
Atsushi turned his head to see Kunikida at his desk in the dim light staring at him with a confused facial expression. It was still early in the morning and no one was there besides Kunikida and Yosano who take earlier shifts.
"I just need to talk to Yosano," Atsushi said before looking around the room to spot her.
"She is out right now she said that she was getting more medicine but will be back very soon," Kunikida said looking down at some files.
Atsushi sighed and then walked to his desk and got on to some reports about 5 minutes later the door opened and it was Yosano carrying a brown paper bag filled with different pills and medicines.
"Yosano I need to talk to you about something in private" Atsushi got up quickly and said this to her as she set her bag down. "Follow me," she said as she started to walk out of the room to her surgery room to have a private talk with Atsushi.
They both entered the room and Atsushi closed the door behind him and looked up at Yosano. "I need your help, I have been having this weird feeling lately...I have been feeling really hot even though it is in the middle of winter and I don't know what to do at all". She just stared at him and told him to sit down in the chair. She had taken his temperature and he had seemed to be normal for some reason.
Yosano was having trouble trying to find out what was wrong with Atsushi, but then it finally hit her.
"One question before I will tell you what is wrong," Yosano said looking at Atsushi who seemed very confused, "do you know if your tiger ability is a female?"
Atsushi looked stunned, he had never thought about that before, "No, I have not thought about that before, but how does that have anything to do with this?".
Yosano started to sweat nervously "Well...uh don't get mad or anything but I think your tiger ability is a female tiger and you are experiencing a heat cycle right now as all female tigers do around this season..."
Atsushi sat there stunned about what had just come out of Yosano's mouth.
"W-What?!" Atsushi started freaking out. Yosano quickly calmed him down and started talking again, "Calm down Atsushi! I think I might have heat medicine in my bag just wait here a second..." she said as she got out of the room and walked down the hall to her desk that had her brown paper bag on top.
Atsushi sat there nervously hoping she had the medicine. She finally came back with a smile on her face and handed Atsushi a pill bottle, "Here, these are the pills you need to take every 3 hours. It helps calm down your heat cycle and trust me you will need it once when you feel it gets worst in about a day. Do not forget that you can not take more than 2 every 3 hours otherwise you will overdose."
Atsushi just nodded along and took one of the pills before heading back to his desk and getting back to work with the pills by his side.
**Timeskip to about 5 hours later**
Dazai was walking by Atsushi's desk and grinned when he had a new idea.
"Hey Atsushi! I have a new mission for you but you have to work with Akutagawa, anyways here is the paper and now I gotta go bye~!"
Before Atsushi could say anything Dazai ran off. He sighed and looked at the case. The case was about a planned drug meeting that they had to stop but when he had gotten to the final part of the case he saw a note left by Dazai saying that Akutagawa was in his car waiting for him outside right now.
Atsushi panicked and quickly grabbed his bag. He hated making people wait. He ran out the door and rushed downstairs til he got to the door and saw a tall figure standing next to his very expensive-looking car. Atsushi started to wonder how much does the Port Mafia makes actually, and why is it more than the ADA. He quickly put that thought out of his head and focused back on the case and ran outside to the car.
"Took you long enough!" Akutagawa said giving Atsushi a side-eye. "Come on get into the car so we can start this mission already," He said starting to get into the driver's seat. Atsushi got in the car and then they drove off.
The car ride was completely quiet, no one dared to say a word. Atsushi started to feel a bit hot again and grabbed his bag that was sitting in his lap just to realize he had left it on his desk back in the office.
A/n:
(Fun Fact: Dazai knew about Atsushi's heat since he overheard Yosano talking about it to Ranpo so he decided to give Atsushi a case with Akutagawa since he is one of the biggest ssk shippers out there)
