Momoko and Nana-chan stare at each other with unsettled eyes. Perhaps, after a few minutes since their first meeting, they already recognized each other as rivals?
「Nee, Nana-chan? Perhaps……it’s just my thought but, seriously wanting to get married with Nii-chan……you don’t intend to do that, right?」
「It’s not perhaps, the marriage is already established, you know? Because, last night we already slept together, and we kissed a lot」
At that moment, Momoko launched a direct physical attack, unlike Nana-chan’s mental attack.
「Nii-chan!? Since the old days, I thought that you were a lolicon, but don’t tell me, even such a baby-like little girl!? If it’s so……I wonder if I must train you directly to only desire me?」
Momoko grabs my by the collar and presses my forehead *gorigori* It’s the feeling of intimidation to the point that it’s possible to be killed by the force. I don’t have the ability to be able to get this place under control.

「So noisy!! What are you being noisy for?」

Yoko-chan opened the door with a sullen face. Although she should have just woken up, for some reason she’s wearing clothes for going out.
「Y, Yoko-chan!?」
「Not Yoko-chan! I heard everything! The onee-chan there brought money for us, so let’s go and eat breakfast first! I will decide Onii-san’s marriage partner after that!」 (Raw: 洋子ちゃんじゃないよッ, it’s 「Don’t “yoko-chan” me」 kind of meaning) 
Without time to be puzzled by the too rapid development, everyone who finished changing followed Yoko-chan and rushed to the entrance.
「Onii-chan, Yoko-chan said……you would take out outside to eat…… That, laundry…….after going back, I will do it」
「Oji-san! You will take me to the shop after all! I love you! If the money is also not enough then you can use Asari’s money, you know?」
「……Onii-chan, are……it’s fine after going back from the breakfast……right? Returning it as dirty as it is is fine too」 (汚れたまま返してくれてもいいから) 
In this situation, the eating out is unavoidable. Besides, I can avoid this bloodthirsty situation for the time being. (それに、そのほうがこの殺伐とした状況をとりあえず回避できるしな。)

*Gacha*……

The not-locked door opens slowly. Reika-san peeked from the gap with a timid face.
「ano……S, sorry!!! I understood Nana-chan’s serious feeling thoroughly so……the form of love differs from person to person, right……t, this, thinking of breakfast, there isn’t any deep meaning in particular!」
Putting the bag at the entrance, Reika-san ran away. Inside, there were lots of sandwiches suitable for breakfast.
「That trembling manner, what in the world!?」
When I picked up the bag, I noticed the gala-phone dropped nearby  Perhaps it’s Reika-san’s. It was opened, when I picked it us as it was, a mail screen was opened. (ガラケー, the traditional j.a.panese-style cell phone)

「Onii-san’s bride is Nana! If you fall in love with Onii-san, I will ○ you! The baby in your stomach is not onii-san’s, right?」 (it’s ○す in the raw, maybe 殺す – kill?)

I was able to check dozens of mails full of such insanity. As expected, this……I had no choice but to feel the cold thing on my spine.
Perhaps, while I was sleeping, she got Reika-san’s email address from my smartphone. I asked and registered her phone number and email address for emergency contact.

「Onii-san, firstly, the onee-chan called Momoko, I must “exterminate” her, right?」
「Nii-chan, I can pin that girl down with force, right? After breakfast, will we show her our love activity?」 (私達の愛の営み)

My marriage (?) partners are about to remove their obstacle at an unintended place? In the first place, am I a lolicon? Do I love another’s wife?……Before that, am I a S? Or am I a M?
