An adaptation of a Korean-American novel, 'Personal Taste' is a play on Kae In's name which literally means "personal" in Korean. The heroine, Kae In, is a troublemaker who is clumsy and awkward. She naively trusts people too easily, thus constantly suffers heartaches, but never loses her cool spirit. Sick of relationships, she hopes to befriend a gay man. As luck would have it, Kae In meets Jeon Jin Ho. Through their time together, Kae In's frustration with being single disappears. She rediscovers herself and grows into a sophisticated, mature woman.
