@kyoonchuu I think the author is onto something. Because I've met guys like Jihyun, and they're super attractive. My friends and students who date these type of guys don't know they are being manipulated until the trauma has been done, and they've had to undergo therapy. (They thought all these jealous outbursts were romantic.) They've been isolated from friends, gaslit to death, until they start questioning themselves. It takes a steady self-esteem to be able to shake yourself out of that. Oh, and these guys tend to be extremely popular, so yes, even IRL people will defend them.
I'm a 40+ old auntie who likes BL. My husband calls them the "anti-husband system". 😅
