This story follows Yunjae's difficulty in maneuvering life due to his condition of not being able to feel most emotions. The book is divided into four parts which are well organized and defined by his different relationships with other people. Family, friends, and his curiosity of feelings. This was a smooth read that kept my attention the whole time. It felt fast-paced and the plot moved along nicely. It is not easy to relate to Yunjae but as a reader, I did feel empathy for him the whole time. I did not expect the ending but that is because Yunjae's actions were not expected. It was a lovely ending and I wholly recommend this book.
