Hyomin cheered on Girls' Generation's comeback as she tweeted, "Soon Kyu who said she's sorry for not being able to come to the premiere party and is busy but came all the way to my house... She even did the 'Jinx' pose to promote the movie before she left.. Although it's embarrassing.. You are such a cool friend....!! I hope this album becomes daebak no matter what~~~ Mr.Mr.♥"
