F. Mitsuki's FamilyXXXX

I remember that all humans born in this world have their own goals. And I think, this is the purpose I was born in this world.

Now I have to focus on investigating the murder case involving Kenkyo.

I'm still with my stepmother-in-law.

A pair of black-rimmed glasses adorned her eyes.

Mother of mixed blood. Her mother is a South Korean citizen surnamed Park. Her father is a native of Japan, the Ainu tribe.

Before marriage, mother's name was Hanasaki Yumi. But after marrying Kim Jaerim aka my father-in-law, then my mother's name changed to Kim Yumi.

The world knows, both South Korea and Japan adhere to ius sanguis. So, which country are we citizens of? bipatride or multipatride? Oh what's the name.

"I heard from your father, Kenkyo is staying at police office."

Oh, so now my father-in-law is my stepmother's gossiping buddy? Hmm ... they are indeed rich people who are strange.

I nodded, my gaze still on the paper containing the victim's data file that I knew named Tamaki.

Mother approached me who was still struggling with the file.

"Okaa-san's friend isn't home today? Why bother me, um?"

I teased my stepmother a little by addressing my father-in-law as his friend. Right? Sleep buddy I mean. I'm really close to my stepmother.

Mother pinched my arm.

"Sleep! It's late." Mother rubbed my shoulder. She treated me like her own son. I know I'm not young anymore.

However, those who have lived in an orphanage since childhood, are of course very happy to be treated like this. I think of my stepmother as my own older sister rather than a mother figure. Yes, because our ages are not too far apart. Maybe only about 15 years.

"Hmm, soon." I said as she told me to sleep.

silence.

I saw my mother looking at my portrait scattered all over the room. Occasionally playing with her glasses.

"Okaa-san looks old with those glasses." I broke the silence.

"Okaa-san is indeed old. Okaa-san's youngest child is already a grandparent."

Hey! So, my jokes were returned, eh? Ah, yes she also knows about my son who has a child. But, I also told them that Jeje and his son died from the virus too. But, they know that I was once a grandfather. Ah, maybe until now. But, I won't say that.

"Kaa-san is making fun of me, huh?" I whined.

Mom laughed, rubbing my head.

I'm forty-one years old. What is wrong? Isn't that still young?

"Oyasuminasai, Jae-kun." Mom said after stopping laughing.

*Oyasuminasai = good night

"Oyasumi, Kaa-san." I answered.

Then mom came out of my room.

And, ah so that's it huh?

This trick...?

The tricks used by the perpetrators are really interesting. Thank you, Okaa-san. Even though Okaa-san doesn't look pretty with glasses, but because Okaa-san wears them, I know the tricks that the perpetrators use.

Correct!

With this trick, without pushing the victim's body, the victim will subconsciously lean her body against the guardrail. The perpetrator does not need to be near the victim to bring the victim down. And if my guess is right, the evidence is in the bodies of the corpses.

Isn't it like I've come across this case before?

But, oh shit! I already know who the perpetrators of Tamaki's murder are, but the available evidence can't prove that that person is the culprit. Besides, I don't know the motive for this murder yet.

***

The only way, I have to meet those three people. And the first is the least likely. The one who called the ambulance.

"Good morning, Mr. Mitsuki." I greeted the man in his forties.

"Good morning. Please come in, Mr. Kim."

I smiled faintly. Not only is there Mitsuki Nakamura, it turns out that one teenage girl is also there.

"He...?"

"She's my daughter, her name is Mitsuki Rin."

Not that. I was about to say, he was the one at the scene besides them.

"I just want honesty. What is Tamaki's relationship with Takumi?"

Seeing the school uniforms that Tamaki, Takumi, and Rin were wearing, which were also Kenkyo's school uniforms made me suspect that there was actually a special relationship between them.

To Kenkyo, she was indeed their 'senpai or senior'.

"Kenkyo-senpai who killed my best friend, why is it my lover that you accuse?"

Oh so that's it? I understand now. I glanced at the finger of her left hand, there was a bandage.

"Knife wound, eh?" I asked Rin.

"W-how... yes, it got hit by a knife."

Alright, now I know the motives and tricks of the perpetrators. If yesterday I thanked mother, now maybe I will thank Kenkyo.

Sometimes female gossip helps too.
