I only picked up Dear Sister for the sake of watching everything Ishihara Satomi has starred in. Going into this drama, all I knew about it was that it about two sisters, polar opposites in personality, and that the younger sister had a secret. I didn't have massively high expectations, so I wasn't ready for all the delicious melodrama I was given! Dear Sister is completely underrated, and proof that Ishihara Satomi is an actress with the golden touch.
