Singer A has been belatedly revealed to have been hostile to train staff.

According to recent reports, famous singer 'A' is receiving attention for showing a hostile attitude to KTX train staff members who asked him to wear a mask during the COVID-19 pandemic. It's said he caused a disturbance on the KTX high speed train in February of last year.

Reports say 'A' wore a bright red jumper and boarded a KTX train going from Masan Station to Seoul Station. He did not follow public transportation etiquette, wearing a mask over his chin as well as singing and talking loudly on the phone.

'A', who looked drunk, also raised his voice at staff members who asked him to wear his mask properly. He allegedly yelled, "Are you deliberately pointing it out because I'm a celebrity?" The staff member is said to have had to eventually apologize after 'A' furthered his reckless behavior and protested in the train's corridors. 

Netizens are currently angry about 'A's behavior and are seeking to uncover his identity.
