Hmmm... I'm not really sure. I never really shipped them together until I read a fanfic about them. Basically I think they just look nice together. They both are attractive and have the kind of "cold" image. You know how fans are though. They ship their bias from one band with their bias from another. I'm actually quite guilty of that myself. I love Jiyeon, so I ship her with almost all my biases from boy bands XD

Although I don't really like other idols to ship with L.Joe but, I find L.Joe and Jiyeon quite cute but they don't match
