The next day, Guo tells the coach that the reserve team is going to play a friendly match against the seal club, which means that Guo will have to stay at the training ground during this time. The coach is excited about the upcoming match, which he believes will be a "revenge match" between the two clubs. The seal club has already beaten the national team in the field, and the reserve coach is sure that the seal team will be able to avenge their loss. Guo is also excited about this news, as he is a swimmer who has won three gold medals in the street swimming competition at the age of 20. He is also a member of the 200m and 800m freestyle relay teams.
