Did anyone read the chapter 77, I don't understand the first part between the B and the A. Have they met after the O incident yet?

I have not translated to read recent chapters, but in chapter 77, the first part where the panels in black background is a flash back with Alpha and Beta, so they don’t meet until later when the beta goes to pack his stuff going by newtoki.
the chapter numbering on newtoki is off, it’s showing a skipped chapter and the last one is 79 they also are not updating properly because 77 is incomplete so I check a Vietnamese site where it’s properly updated till 77.

That’s the Vietnamese link where 77 is complete, there are lots of advertisements, just close the pop up windows.

Y'all forget chapter 24.
The Prof might be family member of the guy (wrongfully) accused of kidnapping Wooju in the past. The whole case is sus. Maybe it's a scheme of someone behind Jiheon (literally), using the young Jiheon and Wooju to take the National Assembly's candidate out. The Prof might be the son studying abroad at that time.

Mr. Kwon just tries to make up for Yeon-oh because his grandfather killed his dad and that night he rapes him. What between them is a transaction, not a romantic relationship, if not for Mr. Kwon, Yeon-oh still have to take care of his dad's debt, being sexually assaulted by that loanshark, strugglling with minor roles. I love how Yeon-oh put some distance between them but it's not fair to put all the blame on Mr. Kwon.
This manhwa made me appreciate all the other red flag/toxic tops, at least they love/crazy about their partners.
