The Beeper(2011)

삐삐가 울린다

Kwang-Soo (Ahn Suk-Hwan) works for a Mobile Network Operator. His primary job is to get users to cancel their pager service and sign up for newer cellphone plans. Lee Hyuk (Seo Tae-Hwa) is one of the remaining holdouts. In order to persuade Lee Hyuk to cancel his pager service, Kwang-Soo makes a trip out to Tongyeong. There, Kwang-Soo learns that Lee Hyuk is still holding on to his beeper, because he is awaiting for his first love to contact him on the device. Kwang-Soo then makes a deal with Lee Hyuk. Their deal is that if Kwang-Soo locates Lee Hyuk's first love, then Lee Hyuk will cancel his pager service.
