if the premises are that unexpected things happen in life and that people sometimes behave in an illogical and inconsistent way, then writing a realistic story becomes really, really easy.
I don't support the position of
moskyx and
Wizard_Shiryuu , because I don't believe in the DIk-Chick system, it's so vague that I don't give it any meaning.
but if the behaviors between two characters do not take into account the "values" that these two characters have shown up to that moment, everyone can do anything
Jill can hire a killer (Bella?) and have Tybalt killed, in life even good people sometimes do very bad gestures
Sage can ask Mc to convince Chad to participate in a threesome, for love sometimes people do strange things
