According to the Chinese edition of Korean news outlet Aju News, there are now home tuition services to help students get better in League of Legends, with each session costing from 5,000 to 200,000 Korean Won an hour. The report claimed that this is due to peer pressure, as students who are bad at League of Legends will be laughed and mocked at, and even left out of social circles.
These actions will apparently cause students (or teens) to have low self-esteem. Some even hold part-time jobs to fund such tuition. Doing an online search in South Korea, there seems to be around 10 websites which provide tutoring and training services for League of Legends, and even Overwatch. According to official government records, 54.6% of teens play competitive online games.
