Theres a new Sunny card now/l8r at Mangoey's, not sure wat cards she's collecting but you could point her at your new trade center n ask her if she'd trade with you. (Btw, ur OP seems to hv a mistyped item, im pretty sure u already hv hyeri card so u cant WANT her card, maybe you meant jihae or Minah, not sure who is missing/owned, just sure its not hyeri. LOL
