Meeting her beautiful Unnie on Queendom 2 made SinB happy since she had been fond of her for a long time. However, SinB would woman up this time and try her luck to get closer to Seola. Then, she begged her golden card slash best friend, Eunseo, to help her. However, the lead dancer of WJSN refused to help and told her to forget her silly crush on Seola. With a new determination, she would get closer to her Idol Unnie with or without Eunseo's help.
