My Stepsister in Kyoto

His lips trembled as he was unable to comprehend what was happening, but as his mental fortitude was strong, Mizuto quickly calmed himself, then looked at Akatsuki firmly, ready to reject her!

Even if he knew that he wasn't a good person, he definitely didn't want to be entangled by such a girl!

Yet, before he was able to voice his decision, she raised her finger in front of his lips. 

"I was joking~! Are you surprised~?"

With a bright smile on her face, Akatsuki said those words as if what she had acted and done was nothing but an act. 

"..." Mizuto.

"But... If it's before, that's what I am going to say, but I know how heavy my love is, and I know how much trouble I will cause to the person that I love so much. Moreover..." 

His body became tense once again as she made a sudden movement by reaching his neck, but fortunately, she only pulled his undershirt and smiled at what she had found. 

"I can see that Yume-chan will kill me if she knows that I am going to marry her stepbrother." 

Hidden inside his turtleneck undershirt were several hickeys planted by Yume. Even though it had been several hours after she had left those hickeys, the marks were still noticeable as she planted them on various parts of his neck and shoulders so strongly.

Still watching his firm and strong shoulders, Akatsuki suddenly fell into silence and just stared at them quietly, but if someone looked closely, her lips quivered as she squeezed her legs, trying to endure something. 

Mizuto didn't realize that and only moved her hand away from his undershirt. "If you know, then don't cause trouble for me, okay?" 

"But you know? I still wish to become your partner and make Yume-chan my big sister." 

"Partner? Not my wife?" 

"Um, a partner." 

"You mean... like a lover?" 

Akatsuki chuckled and asked, "So this made you interested, huh? As expected, you are such a bad guy, Irido-kun." 

"I think that I am just an ordinary man, Minami-san." 

"Well, that's true. You are just a normal man." 

There was no doubt that Mizuto was an ordinary man since he was interested in women, but unlike the majority of men who couldn't have a single woman, he could get as much as he wanted to. 

Even if Akatsuki left him, she knew that he wouldn't be troubled and would just search for others as she was sure that women would line up to be with him. Yet, it was also due to this reason that she was a bit annoyed since the weight on her heart was still minimal, so how did she change his feelings toward her?

 Still, she suddenly thought of something, and her expression became solemn. 

"What's wrong?" Mizuto hoped that Akatsuki didn't think something weird. 

"Wait a moment. I will tell you after this." 

He only raised his brow; then, he didn't say anything, only quietly, enjoying the picturesque night scenery through Kyoto through the Karasuma Line. Nevertheless, when he looked away, Akatsuki stared at his back deeply, in silence, as she thought of an outrageous method to tie him with her. 

Still, even if the two of them were quiet, it didn't mean they didn't say anything, as he wondered whether they were still far away from her house. 

"It's just a five-minute walk from the Takeda Station." 

"That's a bit far." 

Still, when he thought about Akatsuki's trip from Takeda station to Matsugasaki Station, which was about 24 minutes, she needed to travel at least 30 minutes or so to go to school and go home. In other words, every day, she would spend at least an hour on transportation, which made him realize how heavy her feelings were, especially when she tried to stalk him from his home and many other places for the past two days.

"It can't be helped. I chose the Rakurou Private High." Akatsuki then smiled and asked, "Are you not going to ask why?" 

"You want me to ask?" 

"I like this part of you, Irido-kun." Minami then smiled and said, "You know that I have told you that my love is heavy, right?" 

"You did say this to me before." 

"If I have to be honest, if you accept my feelings before, I might lock you up in my apartment so that way we can live the lives of two people together." 

"..." 

Mizuto stopped his steps, wondering whether it was too late for him to run away. 

"Geez, I was just joking. You don't need to take me seriously, okay?" Akatsuki pouted and then put her hands on her small waist. "Look at my body. It's petite, right? I am weak, and you are strong. If you push me now and here, I am sure that I can only accept your advance." 

"...I won't do something that will make me become a criminal, Minami-san." 

"It's not a crime if two people are willing, right?" As his expression changed, Akatsuki said, "Say, Irido-kun, when we were on the train before, I thought of something." 

"...you are not thinking of locking me, right?" 

"Of course not~! Geez~! Believe me, okay~! I am just a weak girl, after all." 

He wondered whether Akatsuki was really a weak girl, but even so, he still held her hand so that she was unable to attack him. 

"By the way, that's my house." 

Akatsuki pointed her finger at the apartment building in the distance. It was quite tall but also a little bit old. Still, the exterior wasn't bad, and as she was willing to show her place, it meant that she didn't have a complex about it, showing the financial situation of her parents wasn't bad. 

"Then, I should go back now, Minami-san." 

He knew that it was a chance for him to go home, but her small hand held his wrist firmly. 

"Say, Irido-kun, I want to talk something with you." 

He took a deep breath, calming the uneasiness in his heart, then nodded. "Is it something serious, Minami-san?" 

"It is since it might involve our future. No, if you don't accept it, then it might be only my future." 

"What's wrong?" He became confused and wondered what this girl wanted to say. 

"Do you know the harem genre in the anime?" 

Of course, he knew, but he wouldn't acknowledge that he knew it, so he thought for a moment as if he were trying to remember something, then nodded. "It should be something that usually appears in the Middle East, right?" The anime aside, it was cooler to use his knowledge of history and geography to show he was a man of intelligence instead of an otaku. 

"That one." Akatsuki nodded. "So I have been thinking, what if you make a harem with me and other girls." 

"...what?" 

"You should know my love is heavy. While I might say that I was joking before, I really wished to lock you in my room and then take care of you for the rest of my life, Irido-kun." 

"...." Mizuto. 

"I know that it is weird and even crazy, but I am trying to change it, although I know that it is hard." 

"Good job." 

"Thank you." Akatsuki smiled when Mizuto patted her head. "But... even so, I get lonely easily. I am clingy. I want to be with you all the time, but I know that it is hard, especially when you don't seem to have an interest in me except for carnal desire." 

"...I apologize." 

"You don't need to apologize since it is normal, and I also feel lust toward you." 

"...thank you?" 

"In other words, I want companionship. I want someone to stay by my side, so I thought, why don't you make a harem, so when you are not around, I and your harem members can be together like a sister? I am sure that it will be fun.

"However, if you fail, you can only be mine, though." 

Mizuto stared at Akatsuki, wondering whether she was joking, but all he could see was a firm decision that wouldn't change even if the typhoon came, which made him speechless. 

"You are not sane, Minami-san." 

To share someone you love with someone else?

He felt like Akatsuki was crazy since if one loved someone, wasn't it normal for them to want their loved one to be exclusively owned by themselves? He couldn't even think of such a possibility, yet this girl dared to say such a thing to him as if thinking that he was a saint who wouldn't bite and just let her play with him. 

"I know. I feel like I am crazy thinking about sharing you with someone, but... I feel like I regret for the rest of my life if I miss you." 

Watching her sincere expression, he just wondered whether his face was so handsome that he could make this girl fall in love with him so helplessly. Still, when he wanted to say something, his tie was pulled so suddenly so as not to make his neck choke; he followed this pulling motion before he was kissed once again. 

Still, this time, he put his tongue inside her mouth, letting her know who was the dominant between them. The silent hunter had been pretending to be prey all the time, and she just fell in a daze as her body quivered many times, and she really loved this feeling. 

"You are going to regret this, Minami-san." 

Minami panted, biting her lower lip seductively, thinking about their previous kiss as she heard his low, growling, beast-like voice. She didn't look away from him and kept staring at him with a haughty yet lewd smile. "Try to make me regret my decision, Irido-kun." 

There was no way for her to regret her decision since she knew if she didn't do this, it was impossible for her to be his memorable.
