(Spoiler) Why the woman escaped in "Possible Love"

If you've seen the movie, it's not hard to figure out, but let me summarize it for you:
After watching her husband secretly go into the forest the night before to scream and wave a stick around—
In other words, seeing him freely release the desires he had been suppressing—
She also felt the urge to release her own suppressed desires and sexual drives.
So, she stood next to a handsome man, flaunted her body, and let her seductive instincts run wild.
However, that doesn't necessarily have to lead to sexual intercourse.
She already felt enough euphoria just by succeeding in seducing the man.
You might wonder why the movie absolutely had to include sexual expressions out of nowhere,
but sex is the root of all human desire.
Going to work, going on strike, or making money—it all stems from sexual drive.
Whether it's "Peppermint Candy," "Poetry," "Burning," or any other film,
any movie that deals with humans cannot avoid the inclusion of sex.
