Original Webtoon

"With this reality-bending ability, I will reshape the surroundings of my dull and gray youth!"

A calm, cool-headed "little brother" who's good at cooking.
A cowardly "male childhood friend" who needs to be watched over.
A "male junior ace" from the soccer club who's got a big ego.
I refuse to have my youth be defined by them, so without further ado...

I turned my little brother into a cute and family-oriented little sister.
I turned my childhood friend into the type of girl anyone would want to protect.
I turned my junior into a cheeky female sports club manager.
The finishing touches are simple.

While the three of them are confused after their sudden genderswap, I will carve the reality that "You are a female." into their bodies, making sure they fall.

Volume 1:

When an introverted run-of-the-mill girl who has never fallen in love or had sex is called to the gymnasium storage room by someone she likes...
Awaiting for her there was a group of sadistic good looking bullies from her class.

They start with teasing her breasts... even though she doesn't want them to... and wishes that they would stop... it feels so good, and... oh please tease me more~!!

In the face of her unexpectedly cute and erotic reactions... the sadistic bullies become bolder and bolder with their actions...

Unable to resist her cuteness, they kiss her, tease her clitoris, and perform intercrural sex in an attempt to make her feel good...
Considerate of her being a virgin, she is gently penetrated, but... it feels so heavenly that she accidentally calls out another guys name...!

Uh oh...!
