Allergy is pre-release and QUEENCARD is title of "I FEEL" album. Allergy released before Queencard 1 week. Allergy is about how people unconfident in themself at present day, in social network everyone look good more than them even though it isn't real. Queencard is about confident, it doesn't matter how your face or body look like, you just must confident in yourself then you can be queencard/kingcard.
😂😂😂 you should see the teaser movie first. Allergy is the Soyeon's real experience when she tried to be the Idol in the past. People say she isn't beautiful enough to be the Idol.
