My name is Shen Shi, and I have a secret.

On the eve of the college entrance examination, I became an oddball in the eyes of my classmates, a fallen genius, a weirdo wearing a mask in the middle of summer.

It stinks! It stinks! It stinks! Everyone smells the same way!

My sister, whom I spend every day with, smells sweeter and sweeter.

I know my sister has awakened, and I also know that I have become a monster.

A monster unlike any other.

Until that day, when the transfer student and the school beauty found me, a third flavor entered my world.

Something's not right, she's fake.

I must keep this secret.

——

My name is Shen Congxing, and I have many secrets.

My brother is of royal blood, a top predator in the dark world, a monster with double pupils and a terrifying sense of smell.

It was pouring rain that night, and he took me home.

Every bit of his restraint, control, and desire towards me sent shivers down my spine.

Until a rising star joined the department.

Wait, bro? How did you sneak in here?!

I must keep this secret.

Of course, this isn't the only one.

Oreki was admitted to a highly educated high school and placed in Class A.

With his keen sense, he quickly understood what was different about this school.

Just when you feel troublesome, you wake up the system and you can get super power rewards by completing tasks.

Teleportation can allow him to go home and fall in love at any time, and transparency can eliminate his sense of existence.

This life seems good and very energy efficient.

Then I got telepathy.

Sakayanagi Yusu: This school is so boring, but Oreki-san is very interesting. You can [play] with him.

Horikita Suzune: Oreki, who doesn’t study at all, got higher scores than me. Sure enough, I didn’t work hard enough! I studied for 16 hours today.

Karuizawa Megumi: Houtarou, thank you for saving me when I was in junior high school. Please date me on the condition of marriage!

Kushida Kikyo (regret): Clothes can’t retain fingerprints at all, so I just gave them away for free? ! (angry)

"..."

So you usually act serious, but in the end you are thinking about this?
