If the charts and views aren't proof enough that "My Type" is everyone's favorite 'type' of song (excuse the terrible pun...), then maybe Lee Yu Bi and Jung Il Woo's Instagram posts may help you understand just how infectious of a song it is. 

Lee Yu Bi uploaded two clips of her holding a solo dance sesh in a pitch black studio, throwing her arms up in the air and wriggling her limbs in every possible direction. "My Type" is a slow-rhythm song that is a bit difficult to groove to but Lee Yu Bi's got the right moves and she just looks so darn cute doing her little dance. 

Jung Il Woo on the other hand, didn't show us any dance moves but wrote the lyrics on his Instagram. It's clear that the catchy song is stuck in the actor's head! I wouldn't be surprised if the actor sang the song aloud in his car ride.
