Kim Jang-hoon revealed that he received financial support from Kim Hee-chul. On the January 31st broadcast of JTBC's variety show "Knowing Bros," Kim Jang-hoon said that Kim Hee-chul from Super Junior sent him 1 million won. Kim Jang-hoon corrected himself, saying, "The condition at that time was to speak informally," and added, "Actually, it was 1.58 million won."

During the broadcast, Kim Jang-hoon mentioned a mix-up involving his name and Seo Jang-hoon. He said, "There was an article that confused Seo Jang-hoon with me. My mother even called me after seeing an article saying I got divorced." Seo Jang-hoon sympathized, saying, "I saw an article saying I went to some festival." Lee Soo-geun brought laughter by mentioning a fake news headline, "Seo Jang-hoon, worth 50 billion, struggling with financial difficulties."

When Bae Ki-sung revealed a good story about Kang Ho-dong's "Star King," Kim Jang-hoon exposed the "Kang Ho-dong call relay." He recalled, "Juniors get called to Kang Ho-dong's waiting room. Even though I was a senior, I went too. When they said, 'Ho-dong hyung is calling,' I went." Kim Jang-hoon shared the emotional conflicts he experienced in his past relationship with Kang Ho-dong. He said, "I was born in '63, but I lied about my age as '68' during my career. Although there was a 7-year difference, we called each other 'ssi' and had power struggles."

Kim Jang-hoon expressed resentment toward Kim Hee-chul. He revealed, "Because of Kim Hee-chul, I broke up with a female junior I was seeing, and I haven't been able to get married for 20 years." He explained that Kim Hee-chul encouraged him to send an April Fool's confession text, but there was no contact afterward. The members laughed and doubted, saying, "Is it really because of Hee-chul?"

Kim Hee-chul said, "Have you forgotten that I sent you 1 million won?" while mentioning Kim Jang-hoon's financial difficulties. In the past, Kim Jang-hoon had revealed, "I don't even have 10 won in my bank account. I have no savings, no house. My total assets are a 30 million won deposit for monthly rent." He is known as a donation angel who has donated over 20 billion won.

Kim Jang-hoon once appeared on KBS 1TV's "Morning Yard" and explained, "My life is not difficult." On last December's "Park Myung-soo's Radio Show," Kim Jang-hoon disclosed his assets, saying, "I have a 30 million won deposit and maybe 2 to 3 million won in my bank account? Starting the year after next, subway rides will be free. I paid a lot into the national pension, so I expect to receive over 1 million won."
