Though set in different time periods, both stories have a male lead who secretly admires the female lead who is much younger than he. These two male characters are rich and have cold-hearted facades, but are actually kind and gentle. They are also acting as the benefactors of the girls; however, in Glass Mask, the girl is unaware of whom she is indebted to.
