Jang Yoon Jung was revealed to have paid for dental braces of 6 juniors and Lee Chan Won added she also paid for his dental appointment when he was a broke rookie. 

On the May 29th episode of KBS 2TV's 'Boss in the Mirror', Jang Yoon Jung was seen invited to her junior singer Hae Soo's house party. During the episode, while Jang Yoon Jung wasn't present at the table, her juniors started to share how Jang Yoon Jung gave so much to them from gifts to dental appointments.  

Lee Chan Won at the studio added that Jang Yoon Jung also paid for his dental appointment when he was a broke rookie. As panels expressed their surprises, Jang Yoon Jung said there are 6 juniors that she paid for their dental braces. She said it's because the front teeth are important for singers. 

Meanwhile, Jang Yoon Jung herself had long obscure days as a rookie singer for about 5 years. She revealed she suffered from malnutrition back then and she almost gave up because she was so lonely. Now that she is extremely successful, she said she wanted to let her juniors know that they aren't alone.
