In the novel, Chase became close to both Nero and Anastasia during the Mock War.
Although he started seeing Nero as a love rival not soon after the Mock War ended, he still considered him a close friend.
By the current point in the novel, they had become good friends. So even when the whole class was shunning Nero, Chase sat with him.
So in the story, when Yelena asked Nero to choose a destination for the class trip, Chase helped Nero by giving him a city name he wanted to visit.
However, in this world, Chase never got closer to Nero since I interfered with the plot. Although I earned some Edit Points from it, now Nero is all alone.
This means there's no one who'll convince him to name a city for our trip, as he has no interest in things such as vacations.
However, I really need to visit the same city they visited in the novel. I need this class trip to head exactly where it was headed in the story.
