i dont get it they implied that baek sa eon is actually the son of the grandpa but if they did a dna test of him and his current playing father it would've been a match too because they both have the same father...?
swore i wouldn't start the drama before it finished airing but here i am having binged all the episodes and now i CANNOT WAIT I NEED TO KNOW WHATS GONNA HAPPEN NEXT AGHHHHHHH
