Sharing Many Common Interests (Rap Monster/J-Hope x Reader)

You and six of your female friends are part of a K-pop girl group called GVA, hiding your true identities by wearing masks. The seven of you wish to be a famous music group like BTS, your favorite K-pop boy band. Along with the girls, you're not yet ready to reveal your identities to the public. But despite that, one of the BTS members is your favorite and like a male version of you whenever you sing. One night while you were hanging out at a nightclub with your friends, you're able to encounter BTS, who is also at the nightclub. They noticed you seven after your favorite member watched you and your friend dancing on the dance floor. You get to talk to him afterwards.

What would BTS think of GVA? How is your favorite member gonna react if he tries to figure out your secret identity while he starts to grow close to you? And what will happen when you and your friends find out you all have so much in common with the boys?
