Four Strangers meet in university, become best friends for two years, then one mistake finished everything.

okay i ll rewrite it , thank you so much for your opinion, Soon i ll uploaded my new logline :)

Okay, but in your amplification of your logline, the focus seemed to be on the relationship between two girl best-friends, a relationship that gets complicated and finally destroyed by the guy. (Which would seem to make the guy the antagonist.)

My primary concern about the logline is that it lacks a hook, something specific that immediately grabs my interest, that sets it apart from similar stories. "One mistake finished everything" is vague rather than specific. There are a 1,001 mistakes that can destroy a relationship. What is the specific mistake that sets this story apart from the 1,000 other stories where a mistake destroys a relationship?
