When the hot summer comes, spring Yoshisuke (voiced by Gutani) and Miyagawa Yuan (voiced by Miyagawa) usher in the most important moment of their life. The college entrance examination is just around the corner, and they work hard for the ideal school in their hearts. At the same time, the tacit understanding between Chunri and Nian Chuan grows with each passing day, but no one knows what will happen tomorrow. On the other hand, the cheerful and naive Hiroyama Kuang (voiced by the original Sakayama) took part in the draft for song and dance dramas, eager to step onto the center stage of New York one day. Seeing that the beloved spring is busy all day, but can not lend a helping hand, this pure girl can only send sweet kisses as encouragement. Such a small move will of course make the thoughtful Nian Chuan find that she and Chunri fall into a cold war, and this love triangle seems to be on the verge of a showdown. This film is based on the original comic book of the same name.
