Suwa's the kind of guy who brings energy to any room—super outgoing and genuinely loves spending time with his friends. As a classmate of both Naho and Kakeru, he's become part of their core group, and he's pretty self-aware about the dynamics: he knows Naho has feelings for Kakeru, and rather than make things weird, he actually supports both of them. It's not really his style to complicate things.
What's interesting is that while 16-year-old Naho has no idea, Suwa ends up becoming incredibly important to her future. For now though, he's just the reliable, upbeat presence in her life—someone she can count on, even if she doesn't realize how much yet.
