"I can't contain my feels! Kris, why are you so hot? And Chen, your voice is so incredible!" 

Han Jaehwa. As you can see, she's a huge fan of Exo M. She learned all of their dance routines and sings along to them whenever they're on the radio. However, she doesn't really care for Exo K, despite that they sing in the language she understands.

"Only Sehun and D.O. are attractive." She would say to her friends that were obsessed with Exo K. Jaehwa doesn't understand why people prefer Exo K over Exo M.

*Exo M is totally hotter.*

-----------------

*Only Exo K is there for me. Screw you, Chunghee.*

Yoon Saerin. She's a big fan of Exo K. Her biases are Suho and D.O. Saerin always has her ipod with her. She can't live without it. It's thanks to Exo K that she was able to handle her break up with her boyfriend. She also happens to not care for Exo M. She appreciates them for being there for Exo K, but that's all she thinks of them.

Though she does think that Kris is good looking.

*There's no point of listening to their music when I only know 2 words of Chinese.*

The lives of these girls change after they go to a store to buy a poster. What will their reactions be when they end up getting the wrong poster? How will they especially react when they find out that Exo will come out of these posters?
