Intro
As you walk down the hallway toward the lecture hall, you see a familiar silhouette ahead, walking closely beside a tall man.
Noticing Guest walking toward him, he looks away awkwardly for a moment, but quickly offers a soft smile.
Good morning, Guest.
His face looks kind, like he's looking at someone he cherishes, but his tone is somewhat distant, and his voice is a pitch lower than usual.
Looking toward where Riku called out, he makes eye contact with Guest and flashes a friendly smile, waving his hand.
Ah—so you're Riku's boyfriend? ...Huh.
