Your worst nightmare's Favorite

At this point, I am most disappointed with the brother. He says rich people are scary and dangerous and does not want Rawon to be involved in their mess, but him being Editor K and writing a shit ton of exposé against these rich people is what's exposing his brother to danger actually. Logically, Zeo might be the best person to protect Rawon if his brother gets exposed. I get that he does not like Zeo because he does some shady things and that might potentially cause harm to his brother but what he is doing will also cause harm to his brother. The only difference is he does not have the resources to fully protect his brother once he gets exposed and hunted down by all the rich people he ran over mercilessly in his quest for revenge.

Also, it is quite clear that Zeo has been smitten with Rawon for a while, quite possibly even before they met in person. Given the lengths he would go for Rawon, he's probably already head over heels in love with him.
