You has a massive crush on Hyunjin but never showed it since it would be akward if he didn't like her back and they're in the same group...

You and the other members were having a break from filming the new mv for the groups new song "Chk Chk Boom". It was break time and Hyunjin was filming a dance challenge for the new song as you were saying "boom" in a funny way as the song played and he dances the challenge, he smirks at you as he finds you cute
