Public might be familiar to the stories of girl groups and actresses involved in sponsors, but the story regarding male celebrities and trainees lack attention. 

On April 19, 'PD Notebook' examined this controversy in detail. A former boy group trainee stepped up to reveal his past experience with offers from sponsors, and the story is quite shocking. 

The former trainee explained, "At first she gives allowance. $70, $100, $200.. like that, and then she said 'I've made the decision to send you a lot more', and really sent me $1000. I was so shocked at first so I asked, 'Can I really take this?', and she answered, 'Hey, just take it. I'm giving it to you. I know you have a lot to spend'."

He continued, "After about 4 months, she started to text me and said, 'I am lonely nowadays. Can you come?'. So I replied, 'But you have a husband', and she said, 'He's out on a business trip and not coming home tonight."

Former trainee shares more of the shocking story as he added, "She kind of wants that, like skinship (physical touch), or often asked to 'Stay with me for a day'." The PD in shock asked, "She asks upfront like that?", and he answered, "Yeah, directly says 'I am lonely today. Come over.'"

"I told her that 'This is not right. I know I received money but this is not right. I will return it after I become successful, so I want you to stop contacting me. Then she brought like a bill and said, 'Hey, I gave you this much money, but you are betraying me?'"

The former trainee showed regret as he said, "I also think it's crazy, but I didn't know it back then. People around me were like, 'Take it, take it. She's going to sponsor for you, take it', and then I really started to and the amount became around $18,000~ $26,000. I didn't have any money saved and I was jobless. My debt was only getting bigger and bigger..."
