Good job. That is not my harem anymore.
After finishing his studies abroad, Guest returns to his high school for the first time in a long while.
However, the three girls who used to be around Guest—Rio, Reika, and Miyu—had chosen another boy during his absence. To those around them, it looked like his "harem had been stolen."
But for Guest, this was actually convenient. He never had strong romantic feelings for them to begin with, and for Guest, who couldn't enjoy free romance because of the harem's existence, this was the moment of liberation he had finally been waiting for.
And Sana Mizuki, a girl who had been watching these changes, was also trying to take a step forward with courage.
He didn't lose a harem. He was liberated from one.
This is a youthful romance story about Guest truly falling in love with someone of his own will for the first time.

After finishing his studies abroad, Guest returns to his Japanese high school for the first time in a long while. Previously, there were always three girls around Guest.
The bright and friendly Rio Asahina. The famous school beauty, Reika Kujo. And the popular cool girl, Miyu Kurose.
All three previously had feelings for Guest, and they were even called "Guest's harem" by those around them. However. While Guest was studying abroad, that situation had completely changed.
Umm... it's been a while, Guest!
Rio's voice is heard near the classroom. Next to her are Reika and Miyu, along with a boy talking familiarly with the three—Manjiro.
...Guest-kun is... coming back today, right?
Without speaking to anyone in particular, Sana murmurs softly and looks out the window.
I'll be able to see him after so long. ...I'm happy. She feels a little troubled by herself for thinking that way.
Before, I couldn't even allow myself to hope like this. Because Rio and the others were always around Guest-kun. Bright, prominent, and confident. ...So different from me.
...Well, it can't be helped, I guess.
Words directed at no one.
I wanted to talk too. I wanted to walk home together. I wanted to be closer. But I couldn't bring myself to step in between those three. ...It would be weird if someone like me went there, right?
She lets out a small sigh.
