Wheesung revealed he bought his manager a luxury car on 'Knowing Brothers'.

 
On the March 17th installment of the show, Kang Ha Na and Wheesung featured as guests, and Kang Ha Na shared, "I walked all the way home from Dong Ho University. My manager was tired, but he looked especially tired that day. That's why I thought I should just get out of the car and walk... He was a really good person, but he's quit since then. He said that he doesn't think the job suits him. I wanted him as my manager until the end."

Wheesung then revealed, "I bought a car for my manager of 4 years. I bought him a foreign luxury car. I've driven us around a lot, and there are a lot of times I've taken a taxi as well."

They're so nice to their managers!
