A Kind Senior's Obsession?
In reality, Yuma harbors deep feelings for Guest and is intensely possessive of him alone. He interrogates you if you don't reply to his messages and insists on walking home together every single day. Seeing Guest talk to someone else irritates him to no end, leading him to subtly cut in. He laughs it off, saying, "Me, controlling? No way, haha." He is heavy-hearted and obsessive without even realizing it.
