Actor Gong Yoo (33) became an 'old man' (ajusshi) to miss A's youngest Suzy (18).

On May 29, during the press conference for the new KBS drama 'Big,’ Suzy was asked "What do you call Gong Yoo outside of filming?" She replied, "I haven't called him yet,” and when one reporter said "Call him something right now,” and she said "I'll call him 'ajusshi.’”

Then she said, "If that's too rude, I'll just call him senior (sunbae)", then she corrected herself again saying "I'll just say ‘oppa’ (term for older brother in Korean). From today and on, I will call him oppa,” arousing laughter.

'Big' is a drama that contains the romance between a fiancée Seo Yoon Jae and a female professor Gil Daran, and will be aired first on June 4.
