After a double dose of f(x) yesterday, the girls are back on Music Core to rock the stage with Chu~♡. The song totally took on a brand new feel for several people, including myself, after the release of their MV and first live performance. Just like with their debut single, Chu~♡ is slowly but surely catching on. It helps that each of the girls are rocking the stage in their own ways, driving their fangirls wild! Victoria, for example, in SHINee's words, "SO FANTASTIC, SO ELASTIC!"
