His sassy comments are often like a satirical comedy on the industry. K3y lived some time in America so I think he is more "woke" when it comes to these issues but he's very adaptable and knows how to get to the top. When sh1nee debuted he used to be the least popular member because he didn't have any gimmick to make him popular in knetz's eyes. 0new had his vocals, jj0ng had his talent, leadership skills and manly persona, m1nho had his visuals, and T@em got attention for being cute but k3y was left out he was assigned the role of being the "Mom" in the group. The lack of attention from Knetz seemed to have hurt his self-esteem a lot and he was rumored to have done self harming practices something he later confirmed himself. He has gotten better in recent years but many still see him as nothing more than a comedian. He is aware of the sad state of the industry and tries to keep himself free from anything controversial playing along with what the latest trend is in korea to survive.
He cares about T@em a lot when sh@wols asked him how T@em was doing in the military he looked sad and concerned but there isn't much they could've done it's all on the military that didn't take into account T@em's mental health condition and deemed him fit for active duty. There was no way out for him if he had tried to run away or delay the enlistment Knetz would've tored him apart or worse he would be punished under the law so he tried his best to serve honorably despite his condition. It was just a case of bad luck for him. T@em is sensitive but he has a strong will power to overcome hurdles in life, he is the type who won't give up very easily . He's fragile but we have so far never heard of any rumors about him doing self harming practices or attempting suicide since debut and military friends reported he was trying his best to get better which is a good sign
depression and panic can be healed if the person has a positive attitude and will to survive so I am hopeful he will get through this.
