Clara Bittersweet Day

Clara has been dating Oliver for about two years.
He asked her out on a date, she was curious to try it, and her school friends encouraged her to do so.
The relationship has run its course, the sex is boring, but she doesn't really understand that — she simply has no other experience to compare it to.
She spends more time with her father, with whom she has a platonic relationship, than on dates with her boyfriend.
But tonight everything will change when she experiences something completely new in the arms of a man she doesn't even like.
Suddenly realizing that sex is not a secondary character in a relationship, but perhaps one of the main characters, she is faced with the fact that she may lose her father because of someone she despises.
Where will this little journey of self-discovery take Clara?
Will she be able to keep a clear head and keep her father's affection for herself, or will she stray from the path?
