Takane no Hana-san(2021)

A cold-looking business woman constantly mocks and degrades her coworker for his mistakes during work. But secretly she's madly in love with him!

Takane no Hana-san is a romantic comedy series following Takamine Hana, a star performer at a traditional Japanese confectionary company. Polished and capable at work, Hana struggles with romantic confidence—her love skills are stuck at elementary school level. When she develops feelings for Yowaki Tsuyoshi, a perpetually scolded junior colleague, she must navigate the gap between her professional competence and her complete inexperience in matters of the heart. The series explores whether Hana can win Tsuyoshi's affection and whether genuine connection can bloom between two mismatched coworkers. Equal parts awkward and endearing, the show balances workplace dynamics with the fumbling vulnerability of first love.
