Yokohama Kaidashi Kikou, Yunagi no Machi Sakura no Kuni Recommendations
They are both beautifully well-crafted manga with exquisite panel placement and visual flow. They are both treats to the readers who like to take their time reading while carefully analyzing everything each panel has to offer. There is a very well thought-out attention to detail where the visual display is concerned.
They both have somewhat long monologues/narrations that induce feelings of melancholia on the reader.
