1 - XD i remember watching The Heirs while it was airing, in hostel with friends and how everything was just so perfect until Oppa opened his mouth and uttered English! *sigh* That was a hugeee blow and i'm so glad he has improved!! and got more lines even!!!!
2 - I was praying not to hear him speak in English again on the show and thankfully he didn't. He reminded me of Woo Bin from Boys Over Flowers who was forced to mouth random English words. I would cringe each time he said 'yo yo mahn'. Luckily, Min Ho wasn't as bad as him.
3 - Yeah i like them too :)) but it's so funny how that "ALMOOOST PARADIIIISEE" got stuck in our heads even though we didn't like it as much as we loved the other osts XD
4 - That's so true!! That song still plays in my head even when I like the other OST's more. but at least it is better than 'Love is the Moment' from The Heirs. I hated that song so much, would mute my PC each time it played. Ugh!!
