After the Harem Novel's Male Lead Turns into a Girl, My Childhood Friend Is Kyoya Hibari

He was Yi Zhihuo, blessed with a beautiful, gentle upperclassman sweetheart who woke him up every morning. He also had a tsundere little sister with twin tails. His sister was the one who called him "Onii-chan" at breakfast, while his childhood friend lovingly fed him each bite. That's how he managed to get by. Sure, whenever he deliberately overslept, his sister would plant a foot in his stomach and yell, "Onii-chan, you idiot!" But that had its own charm compared to his gentle upperclassman, making him the envy of every guy with both a little sister and a childhood sweetheart.

And that wasn't all. His bespectacled underclassman, who turned out to be a beauty without her glasses, shyly confessed to him. How could he resist such temptation? He accepted on the spot. He hadn't expected his sister and childhood friend to get jealous. He was over the moon inside but kept up a dignified front, reassuring them that they were both his wings and he couldn't do without either of them. Then a random underclassman cursed him...

"Yi Zhihuo, your smug face is so annoying. Why don't you turn into a girl and go to another world!"

And so... he became a girl, and his childhood sweetheart became a childhood friend who was a boy.

He--no, she--now had to prepare breakfast early every day and wait for her childhood friend to come and check it. If she overslept even a little, she'd be threatened with a bite from his cane. She really wanted to fight back. But back when she was a boy, whenever trouble arose, her sister and childhood friend protected him while he hid behind them. He had never mustered up the courage to do anything, so she could only submit to her childhood friend's demands.

Then, one day, she finally realized that the talent that used to make him proud of meeting girls had turned into a knack for meeting guys here.

Like... the prince who stuck her head full of little knives, the delinquent boy with a bomb, and so many more! There were too many for her to count! Every single one of them was a total weirdo. If she could go back, she would definitely cherish her little sister and childhood friend, and never... meet any more girls... probably?

Then she heard her sister and childhood friend say:

"Dream on. You're staying here, so don't come back."

Theme: Childhood friend, does this apology look sincere enough?
