It's Okay to Not Be Okay

The main character of the drama is young Moon Kang Tae. Moon Kang Tae works in a psychiatric hospital. Moon Kang Tae never fell in love and did not even have warm feelings for girls.

At a conference about the release of her new book, she meets two brothers. Moon Kang Tae's brother is delighted with the writer and thinks of marrying her, and Go Moon Yong falls in love with his brother. Later, Goh Moon Yong makes a large donation to the psychiatric hospital where Moon Kang Tae works, and at the same time lies her father. She does this in order to see her lover more often.
