This book confused be a lot. For some reason I had grand expectations. It was very slow, very top-layer while still deeply emotional. I was curious all the way through but also got a bit tired of the extreme slow burn and slice of life feel before the twist near the last part. Maybe I should've just read it in one sitting. But even though confusing and a bit tiring at times the ending (or the last third of the book after the twist) for some reason really got me. And the final scene will probably stick with me for a long time. Maybe Oh San's boring daily life was the point in the end
