Magerarenai Onna (2010)

they are both shows about a person who is peculiar and sticks to their rules and peculiarities and still they manage to make friends.

Stubborn people hiding their true emotions and thoughts coming out of their shell

Both are about people making friends and connection, with a main character who is introvert and unsociable.

Both dramas portray a female lead who is pregnant before marriage. Both of them explain their decisions for keeping the child despite the difficulties present in the society for single mother. Virgin Road is more romance centric while Magerarenai Onna shows how the female lead learns to make friends and how she improves herself over time.

They gave me similar feelings. Although Mondai no.. is a lot more in depth with issues around social construct, they're both about women that aren't afraid to stand for their beliefs and move on with their lives.
