My Sempai was NTR'd by a Charlatan: The Distorted Relationship Behind the Smile.

"I have a boyfriend. Why are you doing this ...... to me?"
During her summer vacation back home, his first girlfriend Mahiru is forced into a "secret relationship" with a flirtatious guy. ......?

April is the season for encounters.
I, Shun Uesaka, left the place where I had spent my entire life due to my father's job transfer and will be attending a new school from this school year.
In this new environment, I'm going to ...... grab the cute girlfriend I've always wanted in my hands!
If things went so well, I wouldn't have any trouble, but I'm going to keep my hopes high.

The first time you see a woman in a bikini, you will know that you are in love with her.
Mahiru continues to be embraced by the charlatan behind his back while she continues her lover relationship with the main character.
There is no way she can go back to her old life now. ......
