Unfinished Flowers and the Chinese word "flower" refer to flower girl-Ichiro Ozawa; "Summer Unknown" and "Summer" in China mean that Si Xia and his wife became lovers in Beijing after graduating from college, but because Ichiro Ozawa wants to be an artist, he can only enter a powerful media company (Harmony) that he doesn't want to enter. But he has some hatred with Su Sisi, who is in charge of recruitment. Ichiro Ozawa realized that she wanted to get back at herself. He didn't want Si Xia involved, so he broke up with Si Xia at the first chance. I didn't expect him to be persecuted and blind in his left eye. After releasing his album, he wandered around looking for Si Xia for a long time (the summer is unknown).
