Stop calling bro-girl code to preaching human decency. If you care for your friend, you don’t want them to be hurt and they WILL be hurt if you have a relationship with the object of their fellings. He is a trash friend/human and she is a dumb ass girl for even meddling herself with such a low person #sorrynotsorry
Spoiler
Both erica and zion read the novel that leo will dump erica immediately for julianna (julianna is the original novel's female lead)
That's why zion doesn't hesitate to approach erica because he knows leo will fall for other girl anyway, it's also stated that zion doesn't know leo hasn't move on from erica after 3 years
He also has complex about his friendship with leo, leo never told him while he was dating erica, he just told him once when they broke up, not to mention the novel he read told him that their friendship will be instantly ruined after both of them fall for julianna
So it's kinda complicated for zion
The prince is now a stereotypical “nice boy”, you know, he’ll be nice if you smile to him and please him but as soon as you show him you are not interested he will try his best to ruin you and make you feel like s-it just... because
