100 Days, I've spent Loving You is a continuation of the book 100 Days. It is recommended to read the first book then continue with this one. This book is mostly a romance- comedy. Compare to the first one, this one will be mostly lighter and more romantic somehow. As haein returns into Jisoo's life. What will happen? Will she accept his love? Will someone else take haein's place? Will Jisoo know the truth? Has haein changed?
