There is nothing wrong with the intimate behavior between boys and girls, but it is really excessive to openly make indecent behavior in class, but it can only be said that the behavior is disorderly and violates the rules and regulations of the school, and they can be punished or warned from this angle.
But the video disseminator is really a "villain" who satisfies his own selfish desires. The couple did something wrong, but they won't post the video online for everyone to see, and they won't spread it. In this way, both boys and girls will face waves of abuse and spit, but if one of them is too fragile to stand, something we don't want to see will happen. I don't think this should be the original intention of the video disseminator.
No matter who the video disseminator is, I hope he can take the initiative to come forward, apologize to the couple and accept legal sanctions. For the couple, I hope they can get out of this matter as soon as possible, face up to their mistakes and correct them.
