Casting

Shin Won Ho - A yogurt-addict. He doesn't like people who are rude and talkative, but kinda awkward how he is rude and talkative too. 

Bae Suji - Another yogurt-addict. Kinda like the female version of Won Ho.

Kim Myungsoo - Won Ho's twin brother. Thanks to him, this 21st century fairy tale was made...
