The MV drama version "Day by Day" means that in the future city in 2330, a girl with super powers, Danee, and her blind sister, Xiao Maria, lived together. Ji-yeon, who wants to be a killer, knows Dana has super powers, so she has been looking for her. Although Xiao Min tried to protect Dany, Dany was taken away by Jiyan. Xiao Min was badly injured and saved.

After catching Dany, Ji-yeon wanted to train her into her own weapon, so she pretended to be Dany's closest dutiful son outside the cage, but the scar on her face was discovered by Dany, and the instant hostility showed her ability, with blue pupils and broken glass, but Ji-yeon was obviously not surprised. Six years later, Xiao Min, who had been in a coma, finally woke up.
