drama with serious theme

just finished [akutou kagaisha tsuiseki chousa] and [kekkon aite wa chusen], now im craving for more
anyone got them non-thriller/crime/mystery/revenge but serious themed drama, like serious slice-of-life, or life problem i guess. also no medical/court-room, or legal/history/episodic drama pls.

probably more jdrama-ish, but would probably accept others too.

Sky Castle - the ratings will tell. 

- Bridal Mask: During the Japanese occupation a man try to integrate in the system but becomes the symbol of the resistance movement in the end

- The Hymn of Death: A man and a woman decide to die together in order to escape their sad lives

- Autumn's Concerto - a rich boy gets interested in a girl that get sexually harassed by her stepfather (theme violence against women)
