An LG Electronics employee has become the talk of the town, as the number of subscribers to his personal YouTube channel has soared to over 10,000 within a week after he promised to donate 1,000 won ($0.7) per subscriber to neighbors in need.

To fulfill his promise, he will now have to donate over 10 million won.

Choi Jung-hyun, an employee at LG Twin Towers in Seoul, made the pledge in a video clip while introducing a kiosk machine installed in the building. This kiosk was set up to enable the conglomerate's employees to donate money more conveniently to families in crisis, undernourished children and injured firefighters.

LG employees can make limitless donations by tapping their employee identification cards on the machine.

"Perhaps 50 subscribers will be the best," Choi said in the video clip uploaded on July 4. "I did not talk with my wife about this plan."

However, after another YouTuber, who has more than 440,000 subscribers, shared Choi's video clip, the LG employee's promise has unexpectedly gone viral on social media.

Choi therefore uploaded another video clip, Monday, to humorously ask his subscribers to unsubscribe from his channel.

"If the size of donation becomes much larger than my monthly salary, I cannot afford it alone," he wrote on his channel. "I will ask for support from my company's executives."

In response, LG Electronics said that the company is considering supporting Choi, so that his good deed does not weigh too heavily on him.

"Once the size of the donation is fixed, we will search for an appropriate donee," the company said.

"We are reviewing whether our company's financial support for the employee is legal and how we can provide such support."
