One of Fu's closest friends—basically her first real friend—and honestly one of the few people who actually gets her. While a lot of people wrote Fu off as weird, this person saw past that from day one.
When Fu transferred to the school, she was pretty withdrawn, but this friend was the one who actually approached her first. It made a real difference; they managed to help her open up a bit and work through some of her shyness. They've stuck around ever since, and their friendship is the kind that's built on actually understanding each other rather than just surface stuff.
