The friend moved to US but her financial condition even got worse. Once the friend asked her to buy an american pair of shoes (which was a bit expensive). After a long time, the friend returned to Korea and received the shoes. In the shoe box, there were a letter and a receipt/pricetag that had been erased. But she found in the part of the pricetag that hadnt been removed that the shoes were as costly as she used to ask.
So netizens guessed this actress was RHY due to her long vacations in Japan and US and gave her a lot of compliments.
