As a loyal fan of Ji Sung, I must admit that the initial premise of My PS Partner didn’t catch my attention. I watched it mainly to pass the time—it had been a while since I’d seen a good romantic comedy—and partly because, if it turned out to be worthwhile, I wanted to recommend it.
Before diving in, let me be clear: this movie is not suitable for all audiences. It contains mature content and should be viewed at your own discretion.

Plot Summary: My PS Partner (Korean Title: 나의 PS 파트너)
The film centers on the accidental but life-changing connection between two strangers. Ji Sung plays Hyun Seung, a frustrated musician still reeling from the end of a seven-year relationship. To make things worse, he discovers his ex-girlfriend has already moved on without him.
Meanwhile, Kim Ah Joong (famous for 200 Pounds Beauty) portrays Yoon Jung, a woman desperate to please her boyfriend—who treats her like an afterthought. In an attempt to spice up their relationship, she dials what she thinks is her boyfriend’s number… but mistakenly calls Hyun Seung instead.
From that steamy and unexpected phone call, their paths cross. What begins as an awkward misunderstanding soon blossoms into a strange but comforting friendship. Both are still entangled in complicated relationships, but their growing emotional connection raises a question: was this “wrong number” actually fate?
