xD I like your slight optimism about the latest episode despite its 'lacking' ending or so they say.
FORTUNATELY! Apparently, this is only season 1. Lezhin has it saying 'Season 1 Finale' for the latest episode. Guess, now that the relationship building (trust and all that without the romance) is done with (hopefully), they can finally focus being together romantically, which includes a proper reply to the confession (since they just acted normally the next day) and etc.
OMG, thank you. That's a huge relief that its not just gonna end on a cliff hanger like that and i will try not to hope too much about seeing too many romantic scenes in the next season.
You leave me with no choice but to grasp at thin air and assume, Taeho accepted him. Also they possibly had sex which got rid of the curse and also why Yeon appears to act lovey dovey when he says he wishes their normal relationship was destiny.
Which means that we may not ever know because this is pretty much a 'PG 13' yaoi, doomed to end up like 'What Lies At The End' & 'Never Understand'.┗( T﹏T )┛
