"Kaminaga, Shuto! What are you doing into my apartment?" asked Shiena, confused. She noticed that Kouko was still pointing her gun at her. "And can you please stop pointing me with something that can kill me in one second?"

The black haired girl lowered her gun. Otoya was still sitting on the couch, barely paying attention to what happened. Kouko seemed to be surprised to see Suzu here. The older girl began to clear her throat, ready to talk and clarify the confusion.

"Well, I think that I'm the one who can explain everything, since Kouko-chan seems to be as surprised as you Kenmochi-san to see me here" began to say Suzu. "The other, Kouko-chan and I saw Kenmochi-san working into a manga café. We deduced that you were living into this neighborhood. This morning, Kouko-chan had disappeared. I knew that she probably wanted to go at the place where you work, so I decided to overtake Kouko-chan and found before her Kenmochi-san's apartment"

"And how do you found where I lived?" asked the brunette.

"I'm an expert to find information" simply answered Suzu.

"And why did you want to find my apartment?"

"I think that it's me who should answer this" said Kouko. "My life is in danger, I desperately need somewhere to hide for couple of days. Since we were classmate before, I thought that maybe, you could…"

"Let you stay here" guessed Shiena. "You know, you could ask me, I wouldn't say no…"

But in her situation, Kouko would probably force the brunette to let her stay.

"Anyway, why your life is in danger? Someone is trying to kill you?" asked Shiena.

"Yes, a group of women dressed as nun want to kill me" answered Kouko.

If the black haired girl wasn't so serious, Shiena would probably thought that it was a joke and laugh. Nuns were probably the least group that the brunette would think as assassins.

"Well, since that everything is clear, it's time to resolve our other problem" began to say Suzu. "When I came here, I was surprise to see Takechi-san. I would never guess that you had this kind of relationship with your old roommate, Kenmochi-san. Anyway, I talked with her and realised that you both need to talk to each other, about your feelings. This is a recurrent problem with young couples these days. They didn't talk with their loved one about their feelings enough"

Suddenly, Suzu grabbed Shiena's arm and headed to her bedroom. Otoya, who was quiet since the beginning, follow them. The older girl pushed them into the bedroom and closed the door.

"You stay here until you fix your problem" said Suzu.

She went back on the couch, where Kouko had stay.

"This is for you too, Kouko-chan. Don't disappear like that without warning me, I was worried you know…"

Suzu let herself fell on Kouko's laps. The black haired girl began to blush a little.

"I just don't want to get you involved into my problem more, I don't want you to get kill because of me, Suzu…"

But Kouko realised that the older girl had fell asleep. Suzu could fell asleep really quickly sometime, probably because of her old age. The black haired girl gazed Shiena's bedroom door.

"She's dating a serial killer who can only have sexual pleasure by killing, but she's still alive. I don't know if I should be impressed or have pity of Kenmochi"

Shiena and Otoya were sitting on the bed, at each extremity. They weren't sure of how looking at each other, they didn't know what to say.

"Dammit, Shuto, who do you think you are? A love expert? A psychologist? It's not like you're much older than us anyway…" thought the brunette, who didn't know about Suzu's disease. "What did you say to Shuto behind my back?" asked Shiena.

"Nothing important. In my case, my feelings are clear, I love you. But it didn't seem to be the same for you…"

"You're always saying that you love me, but how could I trust you if you act like them toward me?"

"Wait, them? Who are them?" asked Otoya.

Shiena suddenly noticed that she said something that she shouldn't say, but it was too late. Otoya rushed toward the brunette and grabbed her collar, before pressing her against the bed.

"Dammit Shiena, with whom do you compare me?"

"With those bullies, those hateful people who were always trying to make my life the more miserable possible!" shouted Shiena.

"But, I don't want to make your life miserable…"

"Every time you acted like a bully toward me, you remembered me these memories that I want to forget. All those horrible things they did to me, the pain I felt because of them, there all come back into my mind when I'm with you, you remain me how miserable was my life because of them!"

Shiena stopped talking, her eyes had begun to be wet. Instinctively, Otoya wiped the brunette's tears with her finger.

"Please don't cry. I'm not like those idiots, I don't want to hurt you, not intentionally. Look, it's my nature to be cruel toward others, you don't have to take this personally…"

Suddenly, Shiena grabbed the serial killer by her waist and pushed her on her back, on the bed, while the brunette was straddling on Otoya.

"Why is it your nature to be cruel? Why hurting others is the only thing that bring you joy? What is wrong with you!?" asked Shiena.

"I don't know! I have always been a horrible person. When I was a kid, I was a nasty bully, probably worst then the one who bullied you. I stop bullying when a teacher seriously scolded me, telling me how bad I was, making me feel like I was a heartless person. He was right, but hey, I was a kid, I didn't even know what was right and what was wrong. I was always feeling empty in the inside, I was always unhappy. There had nothing that I enjoyed by living. I was scared of myself, because of all the bad thoughts I had in mind. I began to think that I was a monster who didn't deserve to live. I thought that until I had twelve years old"

"What…happened?" asked the brunette, stammering.

"I fell in love for the first time, with one of my senpai. But she broke my heart in the worst way possible. I never felt such a pain before. I was seriously considered to kill myself and end my miserable life, but one of my bad thoughts came back into my mind. This bitch broke my heart, so I broke hers…" Otoya began to laugh madly. "…using a scissor! I had never felt something so great. When I killed her, I discovered a way to have pleasure, a really bad way to have a pleasure, but it was better than nothing. I couldn't bear anymore the blank inside of me…"

Otoya pushed Shiena and sat, before grabbing the brunette by behind. Shiena was sat on the serial killer's laps, back to her, while Otoya was whispering into her ear.

"After this, there was a kouhai who fell in love with me" continued Otoya. "I wasn't in love with her, but I didn't want to break her feelings. So I slept with her, but I didn't feel any pleasure. I killed her when she was sleeping, she didn't feel any pain. This is when I had the confirmation that killing can bring me pleasure, sexual pleasure. So I continued to kill, in order to be finally happy. First, I was trying to find excuses for what I was doing, to ease my conscience. But more I was killing, more I was losing my humanity, to finally lose myself into darkness. I became the heartless person that my old teacher thought I was, I even began to kill my victims more cruelly, to torture and sometime even raped them. I became the monster that I was scared to become. The worst is that have no remorse for all the horrible things I've done, not even what I've done to you"

The brunette began to struggle inside Otoya's arms and succeeded to push her. The serial killer fell on her back, still on Shiena's bed. Shiena also fell, beside the serial killer.

"Why are you in love with me, Otoya?"

"I'm not sure to figure it out, but maybe it's because that day, even if you knew what kind of person I was, you let me entered into your apartment. I began to think that maybe the only thing that could bring me true happiness is someone that love and accept me for who I am" answered Otoya, before gently grab Shiena's hand. "And you, why you loved me?"

"I still love you, but I don't know exactly why. I suppose that I never felt so much loved since forever, you're probably the person who loved me the most, even more than my own parents. Even if you can be cruel toward me, I can feel your love for me. We're both miserable, we both need someone else to fill our empty heart, to satisfy our lack of love"

"Shiena, I never felt so happy than with you. You can give me true happiness, while before I was taking happiness from others by force. With you, I don't have to kill in order to be happy, you're special to me, and I don't want to lose you"

Shiena approached from Otoya and gave her a tender kiss on her lips, before snuggling on her chest.

"I also want to stay with you, I feel like my life would be lonely and empty without you" said Shiena.

Otoya hugged the brunette, gently stroking her back. Shiena felt so comfortable into her girlfriend's arms. She closed her eyes, while Otoya kissed her forehead.

"Good night, Shiena"

Before falling asleep, Shiena just noticed something. Since when Otoya dropped the "chan" after her name?
