I blame the author that wrote Haruno as Yukino's twin sister, for this story.

Well, I saw some of the reviews from my last chapters, here are my thoughts on them: The story about rivals will continue, all I can tell you it will either end at the University stage or after. Also, there is more than one rivalry going on. Our beloved antithesis is returning to cause more pain to our hero.

Now about stories about a son-con mother, well I have some ideas and written parts about it down but the story is a crime one. I got the idea from a story about Hikigaya learning about his family secret (his mother is a crime lord). And mix some Nisekoi elements with them. Let say we have a yandere and closet son-con.

The word 'love child' has a better meaning but 'secret child' fits well. After all, my father never had an affair. He loves his wife dearly. But that does not change the fact that we have a family secret, a secret child. Nee-san is the perfect daughter and well-liked, even the staff prefer her. I, on the other hand, was the well-behaved daughter. I was known as the doll by the staff. Yukinoshita Yurika, my twin sister and the youngest one. A child that mother kept hidden. Mother always prefer talent. We were gifted with beauty but we were not equal. Nee-san, as you know, had a figure that can entice. I have an average and slender figure. Yurika had a figure that falls between Nee-san's and my figure. And yet, she was kept hidden because she had average grades. For our mother, that was a factor to keep her hidden. Nee-san and I were at the top of everything, beauty, grace, and top of the class. Father had consideration for Yurika, he got her an apartment that was in a higher class building than the current apartment I stay at.

I care for my younger sister but we are different. That what mother had taught us. Why do I mention this now? It is because of him? Hikigaya-kun. Seeing them together is causing me a headache. But this was unexpected. They met way too early.

I was walking through the mall after I purchase a book to read for the club. I was in search of the toy store to observe the plush section. I wanted to take note of the stock of Pan-san the Panda plush toy. I must have walked past it since I found myself near the food court. It was at this time that I notice a certain boy. That ahoge of his, it became a charming feature of his. I even say it is cute. Or it could be that I'm biased since we are lovers. I got closer to him. I notice he was with someone. I found myself looking at a reflection of a fun mirror. A young woman stands next to him. She was my twin sister, Yurika. She wore a black sailor school uniform, her blue eyes, her figure was curvy, her breast seems to want to burst out of her uniform top. Her black hair falls to the top of her shoulder. Did she get a haircut? She had a knee-length skirt but as she shifts from one leg to the other. The hem of her skirt dance in the air, flow up and shows her mid-thigh.

"Ah! Yukino-onee-san" Yurika spoke up.

"Onee-san?" Asked Hikigaya-kun.

"Let's go to your apartment to speak in private," I replied.

I wanted an engagement first. I wanted him to know me first. I didn't want him to know about her yet. I want Hikigaya-kun to know the real Yukino so he can accept me and maybe even start accepting my family and its secrets. Now is not the time to cry over spill milk.

We enter my sister's apartment complex. She pulled out her card key and inserted it in the slot. It opens the door to the main lobby. At her front door, Yurika unlocked it with her card key. We entered the genkan of her apartment. I close the door behind us. I turn around to notice Hikigaya-kun faced away from the hall. His face was red. I didn't have to ask why. Yurika without her uniform. She was removing her socks. Yurika's skirt and the shirt was on the floor. The mismatch green underwear she was displaying for us.

"You go get change! And you livingroom now!" I command.

"Y-yes!" Replied Hikigaya-kun

"Okay!" Replied Yurika.

Yurika's POV

It all started when I bump into someone by mistake. A teenage boy of average height and build. He has medium-short black hair and an ahoge. His eyes were like dead fish-eyes. I was scared of him. I wanted to run but, I stopped when he called out to me. Yukinoshita in a confused tone. Does he know my sisters?

I was going to ask him when another person spoke up. A teenage girl of average height and fair skin. She has long black hair that spills over her shoulders and down to her waist, and an ahoge that lays flat atop her head. Adorning her hair are two red ribbons just above each shoulder. This person was my elder sister Yukino.

"Wow!" I whisper.

Yukino-onee-san and the boy she introduces as Hikigaya-kun is in my bedroom. It turns out this Hikigaya-kun is Yukino-onee-san's boyfriend. I'm not trying to be rude and eavesdropped on them. I was worried about them being in my bedroom, alone. The discussion they are having is pretty serious. I didn't know my sister felt that way. She was telling Hikigaya-kun about our family situation. The way our mother treated us. How I moved away from the main house, and how Hikigaya-kun fits in. Yukino-onee-san must love him dearly. She asks him if they married they can adopt me into the family again as Hikigaya-kun's little sister. This hears like a marriage proposal to me.

"Fine. I'll do it. We'll adopt her. But Yukinoshita." He stops.

"What is it? Is there a problem?" Asked Yukino-onee-san.

"Sounds like you are proposing to me." He replied.

"Y-you Hachiman." Said Yukino-onee-san.

"My name is not an insult, you know." Said Hikigaya-kun.

I left the hallway before they find me there. I return to the living room. I'm so glad, I can hear and feel my heart racing. I'm getting a big brother and my sister does not hate me. I wanted to cry but I can't. I don't want them to know I was listening to their conversation.
