Painful, but Desirable summary: Do-Yun Cha has made up his mind that he's not interested in finding "true love" and instead, desires a pretend marriage. One evening, Ha-Yeon, an acquaintance from their university club, reveals to Do-Yun her desire to partake in his loveless pact. The catch? She's been harboring a crush on him for quite some time. Can Ha-Yeon persuade him to develop romantic feelings for her? Or will he uncover her ulterior motives? Note: The book has an epilogue and an additional four chapters.
