There are many meta references that I found in this drama.
Before Hang Ah will go to her blind data, she meets with her two friends. One of them said that to her father, she is Hwang Ji Yi. lol (As we knew that Ha Ji Won acted as Hwang Ji Yi in 2006)
Kim Hang Ah screamed at Rain, Kang Dong Won, Jo In Sung, and Hyun Bin. All of them were actually Ha Ji Won’s co stars in her past dramas and MV. Kang Dong Won acted along with Ha Ji Won in Duelist, Jo In Sung in What Happened in Bali, Hyun Bin in Secret Garden, and Rain in his MV.
Let’s play Kong Kong Ta! Lee Jae Ha suggestes to his hyung when they are coming in the palace. *Kong Kong Ta? Please check 1 Night 2 Days episode 371
Royal family dinner. Lee Jae Ha teased Kim Hang Ah as a heodang one. * Actually, it is Lee Sung Gi who is a heaodang. lol
Dae Woong’s aunt congratulated to Lee Jae Ha’s engagament.* Actually, Dae Woong’s aunt aka Yoong yoo Sun was in My Girlfriend is a Gumiho with the main lead was… Lee Sung Gi aka Lee Jae Ha.
