Are there any cards I could offer for you to trade Gahyeon to me so I can help someone else complete the DC set? I would be willing to offer more than 2 if you'd like, even 3 or 4. Hell if you want all of Mamamoo I think that's possible. He is only one away from completing the Dreamcatcher Set and that's the only set he wanted to complete. So if you'd consider it, I'd be happy to help you get Twice or Mamamoo cards in exchange.
