Hoya and Eunji have known each other since they starred together in the hit drama "Reply 1997". They became good friends when on the set, but after the show ended, so did their relationship. Hoya had tried to keep in touch, but Eunji had been too busy to reply. Eunji forgot that Hoya and her had been good friends, but Hoya continued to long for their friendship.

However, Doni from the reality show "Weekly Idol" has left the show, and there are two MC spots on the show. With Infinite and Apink on hiatus, the members of both groups are immediately considered to fill the two spots. Eventually Eunji and Hoya are chosen to be the MCs. Will their friendship blossom once again?
