Honestly, considering how generic the plot is you're probably 80% right
Lol literally just following the basic yaoi plot for most bls but who knows. At the rate JK is taking to change, it may be focused more on the angst and then just barely “enough” chapters of JK and dan being a happy couple at the end to “satisfy” the readers. Idk i hate how long its taking tho and chapter 34 still left a bad impression on me about the author
I think Bj Alex is a good enough answer to understand how the author is so i have low hopes for this manhwa but you're probably right
My prediction is that it has to get worse before it gets better (my poor baby dan). So i guess he will lose the fight, blame Dan for it and f*ck him so bad becuase isn’t his jinx like rough s3x? And he thinks he wasn’t rough enough or something? Either dan gets injured or dan finally realizes he doesn’t like being treated in such a way. While he’s away from JK, something will happen to the grandma. Lots of internal conflict happening with JK after losing his fight and dan. He hears about the grandma, hurts seeing his baby dan in pain, so tries to start chanting for the better. Not full 180 but will try to be nicer and a better seme. That’s my guess
