Two people are just drawn to each other despite social norms dictating that they should not be together. The notion of do you stay loyal to your family or follow your heart is displayed in both dramas.
Both have a very mature storyline centering a grown woman who is having a hard time finding herself. They feature growth and both have their own shining points.
Remind me of Kobayashi Katsuya, Sato Yuki & Nishihara Aki drama Shiro to Kuro....& still 1 of my favorite drama....If you like this genre this is a must watch drama/movie. Sato Yuki always adorable since Kamen Kabuto days.
