The basic answer is the correct answer:

That man is Xia Shu and Tuohai's senior! This is the first letter D in the theatrical version (the third part of the first letter D). Driving a BMW that specializes in running on snowy roads. Very fast. In the first movie, there was a scene in which Tuohai fought for Xia Shu. It was in the first episode. This is the man who called)

For the record, Xia Shu and that man are just dating. Men like Xia Shu, but Xia Shu has nothing to do with that man. The man tried to rape Xia Shu after knowing that Xia Shu likes to explore the ocean. Finally, I chose the top of the famous Akiyama Mountain. But Xia Shu secretly called Tuohai. Tuohai immediately drove to Tyumen when he knew it. When the man knew about it, he took Xia Shu and ran, just touching Tuohai. The two men started chasing in the autumn snow. The result was caught up by Tuohai and knocked out by Tuohai. Tuohai animation hasn't come out yet, so the text of the cartoon is not clear. But you must know that Xia Shu is a good girl! The movie is pure chaos! (Maybe it's because the third part hasn't come out yet)
