i recall in an old interview translated by uchi, shin dong yup said oppa can't dance because he's so stiff. i dont really think so from the dances he performed in various shows or dramas. though most of his dances were silly, oppa moves looked pretty smooth.
on the other hand i think oppa is a bad kisser. not so sure if it's because of conservative kdramas, but i've never seen oppa gave any 'real' and good kiss in any of his screen works. especially in aimh, junsuh and eunsuh's kiss was so horribly done. i saw so many NGs for that kissing scene in aimh, wonder why pd yoon still gave that kissing scene a go with that thick jacket annoyingly got in the way of their mouths like that.
and in ss, the part where son yejin gave him a kiss on the island. geez, even a kid can do much better than that.
common oppa, let's show us some good stuffs next time ...
