although his appearance makes him seem rather cold, wootaek is an extremely cheerful and charming young man who has no trouble making friends. in fact, he's quite the social butterfly and is never actually seen alone. at times he might seem shallow or even judgemental, especially since most of his relationships tend to be rather superficial. on top of that it's no secret that many people have a crush on him but so far he rejected all of them.

wootaek is known for his unceasing energy - he literally seems to vibrate with it. especially when he's excited, nervous or stressed, he tends to be a little too much. sometimes he just doesn't know what to do with all his nervous energy and takes it out on those around him - for example, by getting on their nerves with being noisy or excessive physical contact. because of that it's all the more surprising when he is quiet after all.

wootaek is a very ambitious and perfectionistic person who is never really satisfied with himself. that's exactly why he craves external validation so much and loves it when the attention is on him.
