It's still hypocrisy to act friendly and caring towards someone you hate. It's not wrong to call that out. He approached Naaro with completely false intentions, looking for every opportunity to make Naaro look bad. And the tiger has obviously never been romantically interested in someone before. Telling him to stop being jealous is pointless since he doesn't even realize that's what he's feeling.
Let’s not forget he tried to get Naaro hurt when they were at the park so honestly the trigger calling him out isn’t wrong seeing as he witnessed the whole ordeal and can see his ulterior motives
Who was he to judge how someone acts. He's nice to them even when that crush wasn't around. He's just EXTRA nice when the crush is around. The guy talks like he's throwing them middle fingers and putting shit in their food. I know he's the main lead, but the shitty faces and jealous outbrusts are dry af. Grow the fuck up character from a comic lol.
