I think as far as it's executed well, it will be good EXCEPT if Miae and Cheol ever end up separating, it's one that both hv properly talked abt and each of them has agreed to it, with the promise of reuniting and never separating ever again.
CheolMiae are that ship that will never be separated forever, ever.
Oh also S class and Baekje kids being in touch and never growing distant.
