Chinen and Umika can’t still talk with their nee chan and nii chan, the two of them spend most of the time together and that makes them really close…

 

“that concert sure was fun right Chii-kun…?” asked Umika as they head back home after watching their favorite band’s concert

“hai…I hope they would do another concert…” said Chinen

“’so, I shall go inside Chii-kun…oyasumi…” said Umika

“oyasumi…” said Chinen as he kissed Umika at the forehead

“eh…?” asked Umika then she blushed

“oyasumi…” said Chinen then he went inside their unit, “what did I just do…?” he said to himself

“Chii-kun…” uttered Umika while touching her forehead

 

The next day, Chinen saw Umika talking with Ryosuke…

 

“you’re really good at this Ryo-kun…! now I can understand this math problem much easier…” exclaimed Umika

“you think so…? It’s kinda embarrassing…” said Ryosuke

“why are you embarrassed…? I know…! After school, I’ll treat you to snack because you teach me about this…” said Umika

“eh…?hontou…?you really don’t have to do that Umi-chan…” said Ryosuke

“I insist…I won’t take no as an answer…” said Umika

“oh…ok…if you said so…” said Ryosuke

“you two seems having a good time eh…” said Chinen

“oh, Chii-kun…Ryo-kun just taught me on how to solve this math problem and now I can understand it much easier…!” boasted Umika

“hontou…? Hey Ryo-kun, why is it that you never teach me and when it comes to Umi-chan you teach her immediately…?!” pouted Chinen

“well, you never asked me to teach you…” said Ryosuke

 

After class…

 

“Umi-chan, ikuzou…” said Chinen

“you go home first Chii-kun, I promised Ryo-kun that I’ll treat him to snack after class because he helped me with my math problem…” said Umika

“eh…? Just the two of you…?” asked Chinen

“hai…nande…?” asked Umika

“anooo~…betsuni…” said Chinen

“so, jaa Chii-kun…!” said Umika as she waves to Chinen and go to Ryosuke

“what happened…?” asked Yuto and taps Chinen’s shoulder

“she was not going home with me…” said Chinen

“so that’s why you’re sad…” said Yuto

“what are you saying…?who’s sad…?me…?i’m not sad…” said Chinen then walks away

“now who’s not sad…he’s always denying…” said Yuto

 

As Chinen went home, he saw Aya and Kamenashi…

 

“tadaima…” Chinen said in a flat tone

“okairi…” said Aya

“where’s Umi…?” asked Kamenashi

“she didn’t went home with me…” said Chinen

“why…?” asked Aya

“she has a snack date with Ryo-kun…” pouted Chinen then went upstairs

 

Because Chinen was upset to what had happened and he seems wanted to tell somebody of what is bothering him, he suddenly talked with Aya and Kamenashi…

 

“looks like he’s jealous…” said Aya

“you betcha…” said Kamenashi

 

That night, Aya talked to Chinen…

 

“what’s the problem…?” asked Aya

“ha…?” asked Chinen with a confused face

“I know you got a problem…you can tell me…” said Aya

“nee chan, I think I have to go to the doctor…” said Chinen

“eh…?!!! Why…?!!! Are you sick or something…?” asked Aya

“I guess so…because my chest hurts…this started when I saw Umi-chan talking happily with Ryo-kun and it hurts more when I knew that they would be having snack together…I guess I have a problem with my chest or something…I need a checkup…” said Chinen

“oh, is that what you’re feeling right now Chii…?” asked Aya

“hai…” said Chinen

“well don’t worry, that’s normal…” said Aya

“eh…?it’s normal…?you mean I’m not sick…?” said Chinen

“no you’re not…” said Aya as she pinched Chinen at the cheeks

“ittai…!why’d you do that…?” asked Chinen

“betsuni…I’m just happy because my little brother was growing up now…” teased Aya then she leaves the room

“what’s wrong with nee chan…?” asked Chinen to himself

 

The next day, Umika and Chinen were both shocked to the news they had received…

 

“NANIIIIIIIIIIII…???!!!” said Chinen with a shocked look on his face

“yup, you heard me right Chii, I’m not allowing you to see Umi-chan ever again…” ordered Aya

“but why…?” asked Chinen

“because I just don’t want…I want the two of us to have quality time together and I think that Umi-chan was always around you and that makes you have no time for me…” said Aya

“but that’s unfair…!” said Chinen

“it’s not unfair…and my decision is final…! The two of you were not allowed to see each other ok…?” said Aya

“nee chan…!!!” shouted Chinen

 

 

“what did you just said nii chan…?!!!” exclaimed Umika

“I said that Chii-kun and you were not allowed to see each other from now on…” said Kamenashi

“but why…?” asked Umika

“you’re always around him…the two of us can’t have bonding time with each other and I missed that…” said Kamenashi

“you’re unfair…! Why is it that you can see Aya-chan and I can’t see Chii-kun…?” said Umika

“it’s because Aya is my girlfriend…Chii-kun is not your boyfriend by the way so why react like that…?” said Kamenashi

“demo…” uttered Umika as she think of what her nii chan had said

 

 

At the park, Chinen talked together with Yuto and Ryosuke…

“what’s the problem…?” asked Ryosuke

“Ryo-kun…I feel that I don’t want Umi-chan near you…it hurts on my chest…” confessed Chinen

“eh…?” said Ryosuke

“yeah…you heard me right…why am I feeling this way…?it’s not the same to what I had felt on nee chan having a suitor…this one is much painful…” said Chinen

“I think I know your problem…” said Yuto

“hontou…?nani…?” asked Chinen

“you’re in love to Umi-chan…” said Yuto

“EHHHHHHHHHHH…???!!!” exclaimed Chinen with a surprised look on his face

“I guess Yuto’s right Chii-kun…you’re jealous whenever Umi-chan and me were near each other…” added Ryosuke

“I’m in love with Umi-chan…?” repeated Chinen as he holds his chest

“hai…” said Ryosuke and Yuto in chorus

 

 

At the school…

 

“Umi-chan…!” said Chinen as he hugs Umika

“Chii-kun…!” said Umika as she hugs Chinen back

“they’re mean…” said the both of them in chorus

“why are they making us apart…?” asked Umika

“I don’t know…it’s for their own likeness…they even not considered our feelings…” said Chinen

“nii chan said that it’s ok if we can’t see each other because you were not my boyfriend anyway…” said Aya

“so you knew the feeling now…” said Aya from behind who was standing next to Kamenashi

“nee chan…good that you’re here…I need to tell you something, and also to you Kame-kun…don’t bring us apart again…now it’s clear to me…it’s clear to me that I love Umi-chan…I love her very much…not as sister but as my special someone…so Umi-chan, will you be my girl…?” asked Chinen as he held Umika at the hand

“Chii-kun…”uttered Umika

“Umi-chan, this past days I felt like my heart was being stab especially when I saw you near Ryo-kun…I thought that it was just normal since the two of us were really close and I compared it to my situation with nee chan but it was different, when it comes to nee chan, there’s no stabbing sensation in my heart but when it comes to you Umi-chan, there’s that stabbing sensation which I don’t like I felt that because I love you and you’re my special someone…” said Chinen

“Chii-kun…I also think of you as my special someone…I found that out after nii chan told me to not see you anymore and it was ok since we’re not a couple…it really hurts me because I love being with you Chii-kun…” said Umika

“so does that mean that you agree to be my girlfriend…?” asked Chinen

“yes…” said Umika

“hontou…?! Yes…! I love you Umika…now nee chan, Kame-kun…we were now a couple and we do love each other so I think that the two of you don’t have the right to bring us apart…” said Chinen

“Chii, we were not really mean to bring the two of you apart…” said Aya as she giggles

“eh…?” said Umika and Chinen in chorus

“we’re glad that the two of you feel how to love truly…now you know the feeling when you were being told to get separate to the one you love…” said Kamenashi

“eh…?” asked Chinen

“do you two think that we don’t know that it was the two of you who were bringing us apart…?from the ‘threat note’ until when we’re at the amusement park…?of course we knew that it was the two of you…and your disguise, it didn’t help at all…and as for you Chii, what you did to Yuya-kun was bad…you became mean to him…” said Aya

“so you knew…” said Chinen

“of course…! I’m your sister so that’s why I knew…”said Aya

“gomen…hontou ni gomen to what I’ve done…” said Chinen

“ok, I’m understanding what you feel but you don’t have to do it…even though I get a boyfriend, my love and attention to you would be the same…it will not change…of course I love you…you’re my little brother right…?” said Aya

“hontou…?arigatou nee chan and gomenasai…” said Chinen

“ok, apology accepted…” said Aya

“gomen also nii chan…I’m just jealous with those girls around you…” said Umika

“Umi, you’re my little sister and I love you so you don’t have to worry…I’ll love you even though I’ll get a girlfriend…” said Kamenashi

“hontou…?well, if that’s true I’ll stick to what you said…” said Umika as she hugs her nii chan

“so I guess you’ll stop from being my possessive little brother, right Chii…?” said Aya

“eh…?possessive little brother…?well maybe…but I guess I’m gonna be a possessive little boyfriend…” said Chinen jokingly as he hugs Umika

“hey…” said Umika as she hugs Chinen back
