I'm back with another mashup! This time, it's for Apink's latest comeback, "I'm so sick", together with CHUNG HA's "Roller Coaster". I apologize if this mashup sounds a little messy. It's hard for me to mash songs up without official instrumentals soooo, yeah. I hope you still enjoyed this one!

I do not own anything. All media involved (excluding the mashup) belong to their respective owners.
