Be it consensual or non-consensual (although I think it was the former), or Hyesung is acting like some golddigger, or Dojin is trying to impose motherhood on him. Whatever it is, this story is fictious, and no matter how it ends, it won't affect your lives, just read the story to enjoy. Everyone is entitled to their opinions. So read as the fiction it is, not some autobiographical manga.
I held my breathe reading the chapter till the end, when I let out a huge breathegasm. I'm so fuckin shook to my core. I need an inhaler. The yaoi gods have blessed me.
