Rather than the military service itself. I think it was the thought that he has spent half of his life now that tormented him. And the military is not an environment for a person like him or jj0ng.
He is babyish when the cameras are on. But in Interviews about his solo career he becomes a very serious person. When they asked him about his interests in interviews for Superm promo he said I like Philosophical concepts. His 'Peculiar' interests include Philosophy, Religion, Relativity Theory, Quantum Mechanics and he loves both making and watching documentaries. K3y scolded him for talking too much about documentaries he watched about environmental issues and quantum mechanics during their 13th debut live when he thought he was going to talk about 'fun' things.
If these are his actual interests and judging from the themes he has discussed in his music like his constant struggles with fame and fear of being treated like a product thrown off once consumed it paints him as a very serious person and nothing like the baby persona sh@wols are used to. I have a feeling deep down he is aware of the darkness of the industry and knows the reality of an idol's life. He had probably been using work as a form of escape from his dark thoughts but in the military he had to face all his demons and being constantly exposed to Sasaengs one of the worst things this industry has produced would've aggravated his problems even further. He needs proper therapy to help him sort out his problems and fans need to stop treating him like a baby. There is a difference between being protective and turning someone into a walking meme
He said he skipped kindergarten because the idea of a normal life where every person is told that graduating from college then working for a company is the way to live a good life sounded like brainwashing to him. He didn't want to live like a robot and military is a place where you are stripped of all of your individuality, freedom and taught to act like a mindless robot he was never going to have a good time there.
People say he was different even as a kid. He spent more time in the practice room than the playground because he was so determined to reach his goals. And that determination pushes him to reinvent himself again and again. But it is also something that can come off as an obsession that can consume him similar to how it consumed his idol MJ and many more artists who had tragic endings. His Hyung jj0ng is probably one of those tragedies too. He needs something that saves him from becoming another tragedy even if it's just a pet or his faith.
Fans turned him into a meme and he's called their baby, and even the industry's baby. It's worse than Jk, and I thought no one had it worse than him. I can see him getting depressed in his late 20s for the reasons you said. Many people become depressed at that time.
I have to watch the video and see where he discusses his interests. Watched a video that showed how hard working he is.
He seems to overwork as a way to avoid thinking about or remembering stuff that's happened. That's not healthy, but it worked until the military.
People like him and jjong shouldn't go to the military. It's dangerous to their mental health and physical well-being. I think there's a lot that happened to him when he served, but it's not right for us to know. It's bad enough we know about his mental health and medications. I understand why it was revealed, but it's sad that he hasn't had privacy.
His hyung is one of those tragedies. That obsession was in the video too. He kept repeating parts of his videos to exhaustion. His legs go numb from how much he practices. When he gets out of the military, he needs to take a break, but it would affect his career. Taem1n is very unique for a Korean person, and even a Westerner. He wants to stand out, but lives in a society that destroys individuality. Even my country destroys people who want more than a career, shopping and a drone life.
He reminds me so much of an autistic person. They often see what's wrong with society, but society sees them as disposable and tries to bend them into something else, rather than appreciate what they bring to the world. His hyper fixation on his interests even when it annoys others is another thing that makes me think he's autistic. K3y made fun of how he answered interviews when he was younger. He would answer something unrelated and rock back and forth. It probably stresses him out trying to mask himself in public. We all do it, but not this much.
He has to be aware of the dark parts of kpop. There's no way he doesn't know. His body language when old perverts bothered him, or he was made into a joke shows he knows. I hope he can get help and get what he wants from his life.
