Both of them hiding super important things to one another

Its still unclear to me whats the top is hiding but i guess its obvious he never speak about his feeling to his fiancee directly. I'd die to know when he realized hes whipped ╮(￣▽￣)╭

he's gonna use his body as host of hyeon seol's soul, basically he's going to sacrifice himself

Oh no....thanks for let me know :(
