Orange Caramel released their MV for "Catallena" and had a fan meeting with 50 fans on March 11.  

In relation to the word "Catallena," Lizzy said at the event, "It's a new word so it may be a little unfamiliar but the exact definition is well portrayed through the song, which is about people who are immature and choosy, but strangely enough, others want to become close to them anyway."
