The leading man reminds me of Kang Ma-Ru;s character who atones himself of the mistake he did in the past. How he also sacrifices his life and happiness for people he loves. If you fell in love with Kang Ma-Ru you might also fell in love with Soda Ren.
Fmale lead in my mister remind me of Male lead in Innocent Man. Both gave me the same heartache everytime I watch them. Both actor give me similar performances vibe. dark, sadness in their eyes, and wear their best mask to hide their true self. Both are memorable character for me.
I know they have different genre, bit there are still some similarities. Both main leads are innocent and had to sacrifice for their love; one is love for his lover while the other is love for his sibling. On both dramas, the male lead fell in love with the stepdaughter of their first love.
