I really liked this story, but this is awful. And the MC's way of thinking, that he would rather give into the professor's wishes and have sex with him again instead of telling his boyfriend the truth, it's hard to swallow, (no pun intended). Webtoons like this are rare, but it's kind of hard to read unless this chapter is the professor's imagination going wild again. It's intensely more aggravating than the regular BL/yaoi manga where rape and blackmail is used at the start of the romance. What makes it frustrating is the MC is acutely (probably) aware of it in this story, it's clear to the readers that it's rape, but the relationship doesn't feel like it's going to end any time soon. I just wanna read a happy gay story with a healthy gay romance for once.
