And here we go with the no communication again. Jace is probably going to distance himself from the Duke to 'protect' him from rumors starting. So the Duke will be angry and hurt and then there will be angst and Jace will probably be physically hurt or assaulted in some way, and blah, blah, blah, angst and miscommunication until they eventually make up. This Manhwa is so tedious and frustrating.
Edit: Five chapters after I made this comment and at Ch. 71 nearly every single prediction I made has come to pass. We're at the "Jace getting physically hurt or assaulted" stage. Next comes angst, rescue, and making up.
Ch. 77: And here we are with more assault. We got the physical assault. Now we're getting the sexual assault from the Duke. As if sex is what Jace needs with his back ripped to shreds and bloody after being whipped. We'll either get a separation arc or a confinement arc next.
Ch.80 - boy is this story predictable. Here's the separation arc, and the Duke inappropriately directing his anger at Noah and pretending he doesn't care about Jace leaving.
The end: you know what, I don't even care anymore. They ended up happy with each other, the Duke proudly announced their relationship, Jace gets to be happy. This story wast still utterly frustrating and stupid, but whatever. Happy ending.
