Hmm, those are pretty hard perimeters but, here goes:
Warrier Baek Dong Soo- Its hard to explain, the leads, one is the unsocial type while the other is very outspoken and someone to be admired, a little cocky but not bad.
Vampire Prosecutor- What's cooler than a vamp who doesn't glitter? One who is both cool and lonerish.
Shut Up: Flower Boy Band- Not to sure about this one either, but I say being the lead singer in a band makes you cool.
Iljimae-Kind of a Robin Hood type.
Hope these give you somewhere to begin..
