When the host Super Junior's Heechul asked what makes Park Na Rae swoon, she answered that she likes it when they speak formally to each other in public but informally when together in private. To this, Heechul suggested they enact wall pinning with the show's cast member Rowoon and guest Cha Eun Woo!

Park Na Rae took the lead and provided hilariously romantic and cringe-worthy scenarios of Rowoon coming to her house and Cha Eun Woo telling her she is still pretty with a bare face. Cha Eun Woo and Rowoon also battled it out with their most handsome facial expressions! 

Fellow ASTRO member Moonbin was also on this episode of 'Lipstick Prince', but you'll have to tune in to the full episode to find out what kind of antics these two were up to!
