Glass Mask (1997)

Glass Mask and Skip Beat both follow the life of a soon-to-be outstanding actress.

Both shows are about Entertainment Industry and are Adapted From A Manga. Both of them include an Older Man/Younger Woman relationship with considerable Age Gap. In both shows the lead male has a Hidden Identity.

glass mask is the first season and this sp is something youd enjoy after watching the other 2 seasons

In some views you can't even compare 'Heartstrings' to 'Glass Mask' (there are two seasons), because 'Glass Mask' is better in many ways, but both are about acting and working hard in order to achieve your dreams. GM is not so much about romance as H is, but it shows the reality of being an actor.

In these series, both male leads project a false persona around others. They only reveal true emotion through written correspondence with the female lead without the female lead knowing it is them. Both pairings also have a large age gap.
