Otomen (2009)

In Otomen, Asuka acts like a popular, manly man. However, he secretly likes girly hobbies such as sewing. In Hotaru No Hikari, it's the opposite, Hotaru acts like a typical OL, but at home she's a slob. Ironically, both love interest in these series are the exact opposite of the male/female leads.

This story follows the sweet and “overprotective” newly-wed life between Someya Yukito, a young master of an established inn in Asakusa, and Tsuruoka Io, a pure-hearted female apprentice training to be a chef. Tsuruoka was in the depths of despair until she found solace in the sweet konpeito candy given to her by Someya. Since then, she has earnestly cherished her feelings while training as a chef. Yukito’s affectionate words and actions reserved only Tsuruoka, along with his excessively cute jealousy, create an irresistibly heart-fluttering devotion with a charming gap that’s impossible to resist!

The story lines are different, but the styles are the same. Both the male leads are high school guys who act "cute" and challenge traditional notions of masculinity. Both dramas also focus on the relationship between kids and parents.
