A story about the protagonist's anguish as he discovers that two of his best friends since their school days have been secretly having sex, just as they are about to get married.to be honest, the heroines written by this scenario writer are always so stupid that it doesn't matter if they are erotic or not, they are just unpleasant.

Below is the flow of the story.
I love the protagonist! →The protagonist “non-virgins are good”! Let's lose our virginity with another best friend! → Huh? Are you saying things like ``Virgins are better after all'' this time? →I have to hide the fact that I'm not a virgin! →I finally got to hang out with the protagonist! but until the day before the confession, I was hanging out with my best friend! →I will marry the main character soon! but the sex video was found out by protagonist by accident when he borrowed my laptop →It was before we started dating, so it doesn"t count as cheating, I felt bad for lying, but it was a long time ago! ... Something like that.
If the heroine was simply a cheerful bitch with a lot of experience, she might have been accepted, but even though she says that she loves the main character, she has an overactive sexual desire and a low sense of chastity, and when a problem arises, she easily turns to cheating, so it's completely unacceptable.

Atelier Sakura has a lot of works where the fmc's virginity was given to someone else,so their works where the fmc's virginity was given to the mc's are even more valuable.
