I'm going to say that he was probably the one who initially said he wanted to marry MC, and then forgot about it like an idiot. He's probably the type that gets bored quickly and then tries to change the narrative to convince everyone he never liked the thing in the first place.
I hope the dude is just under a lot of stress from assuming his new duties and been especially cold to her due to hormones or smh. I'd rather see a silly redemption story rather than "he was a jerk to me once and now I am dating an Ace-kun over there" storyboard #99.
thank you for the TL!! honestly, i like a good redemption so im cheering for the prince!! it seems that the stress of taking over as crown peince changed him (+ did he even have time to mourn his brother?) poor guy
theres only a handful of ways these writers write these characters. im putting 10 on the girl is really talented and prince boy got jealous of and/or angry at his own inferiority
it would've been more interesting had the story went
with redemption or something. like she went back to the crown prince as he is also just a victim of the shitty queen and king.
or maybe because the story is predictable having many others with similar theme. or just that the ml doesn't have any appeal to me at all.
crown prince just has more depth while ml's the perfect 1st prince as always and ended up stealing everything from the crown prince, like his perfect mother lmao
