Whatcha Wearin'? (Korean: 나의 P.S.파트너) is a 2012 Korean romantic comedy movie starring Ji Sung and Kim Ah again. This is about a woman who tried to add interest to her five-year relationship, tried to have phone sex with her boyfriend, but unexpectedly got another man online.
After breaking up with So-yeon (Shin So-yul), who had been dating for 7 years, Hyeon-seung (Ji Sung), who became an ordinary toy company employee after breaking up as a composer, is excited to receive a strange phone call. It was an event prepared by (Ajoong Kim), and was connected to Hyunseung by incorrectly pressing the phone number of the boyfriend who could not transfer the phone number to the new cell phone.
Seokwoon (played by Kim Seong-oh) and Young-min (played by Moon Ji-yoon) comfort Hyeonseung, who can't forget Soyeon at a drinking party, but their consolation reminds me more of Soyeon. Hyeonseung can't stand and calls Soyeon, but the sound coming from the phone was Soyeon's new boyfriend's voice, and Hyeonseung couldn't control her feelings of despair and made a phone call to Yoonjung's phone number, who had received a while ago.
