Ever since I was shocked by "Five Centimeters in a Second", I have had inexplicable expectations for Makoto Shinkai's works. His greatness lies in the "combination of emotions in the scenery": the complex and unspeakable emotions of the characters at that time are reproduced through the exquisite animation scenery and the piano music full of fresh Japanese style to create a kind of feeling in the audience's mind. Emotional waves in the film, so as to achieve a high degree of cognitive unity between the director and the audience.
