So, basically from what I read on the novelupdates forum: Hawon gets away from Taeha with the help of taeil (that other millionaire asshole), whom he struck a deal with. He gets raped from taeil who films it and sends it to Taeha. Taeha recaptures him and rapes him again after he tries to run away.
After some shit, Hawon posts the wikileaks to save Taeha from an ongoing investigation? At the end Hawon gets kidnapped again from Taehas father(debatable on the father info) and gets shot in the lung and thrown out of a yacht. Taeha saves him but Hawon gets into a coma.
After he wakes up, he’s left with permanent lung damage and Taeha starts treating him softer because of the fact. They get married, Hawon starts working for Taeha as his secretary.
Anyway, that’s what I read. Hope you understood everything.
Permanently disappointed if you ask me.
I just read the spoilers and I have to say that for that shit ending, Hawon suffered for nothing.
