1. The red stripe of Chinese fir was posted by the weaving department, with the purpose of approaching and kidnapping Chinese fir and luring A Si out. He wants to get back at Doumyouji Tsukasa, because one of his very good seniors was beaten by Doumyouji Tsukasa and his liver ruptured. (MS mentioned it at the beginning of the first movie)

There are convincing reasons, because in the past, Doumyouji Tsukasa disobeyed his mother's orders and refused to take over TD Group, which led to a loyal employee committing suicide because of Doumyouji Tsukasa. Doumyouji Tsukasa felt very guilty, only then did he feel the heavy responsibility as the successor of TD Group, so he promised to get engaged with Xiaozi to consolidate the family business.

In the Japanese version, Doumyouji Tsukasa lost her memory because she fell off a cliff. During her hospitalization, a girl named Nakajima fell in love with Doumyouji Tsukasa and took the opportunity to approach him, but in the end she failed to win true love. Although Doumyouji Tsukasa has lost her memory, her love for Chinese fir will not disappear. He realized that Nakajima was not the girl in his heart (the instinct of the beast? Hehe ~) I finally got my memory back ~

4. Shunping in the second part is equivalent to Xiaoshun who kidnapped Cunninghamia lanceolata in Taiwan Province Province. There is no Qinghe in the Japanese version, and a red bar is posted in Shunping ~
