After seeing in which group I am I had quite a problem finding a suitable song, but I managed to find one I like and decided to use my favorite drama King Of Baking, Kim Tak Goo.
So, something about the video so you'll understand it.
It shows Ma Jun's point of view. He's envious of his 'brother' Tak Goo because he gets their father's love and Ma Jun doesn't, no matter what he does. So he tries to beat Tak Goo in every possible way. Trying to win over father, Tak Goo's love Yu Kyung, but Ma Jun also suffers in his game. He knows he should just stop, because he does feel affection towards his brother and Yu Kyung, but his pride always wins over and he again does something stupid. All because of jealousy and envy.
I didn't want to use a love connected jealousy but rather I put out the problems these two brothers had and especially Ma Jun's struggle with his envy.
I'm not really sure of how it came out but I hope it looks okay. :)
