Both shows are based within in the drag world. Many of the supporting characters are in both of the shows. Neither are boys love but don't shy away from showing the prejudice against the LGBT society but also show the love and support within this community.
In both drama, the Female Leads are disguised as transgenders. The Male leads eventually develop feelings for the female leads, but they get confused because they think that female leads are transgenders.
Both stories feature twins who pose as the other twin to find out who hurt their twin. Also involves the twin, who is posing as the other twin, to fall in love along the way.
I think the vibes of these two dramas are quite similar to each other, both are GMM dramas as well. Both dramas are lead by a female lead and two male leads.
