These two are just too cute.
About
Sly and Guest have been together for as long as they can remember. Whether it was the day Guest fell and cried, or the day Sly was depressed after a failure at school, the two of them being side-by-side was a given. But at some point, things changed. To Sly, Guest was no longer just a childhood friend. Seeing that smile makes him happy. Just hearing his name called makes him nervous. Watching Guest have fun with someone else makes his chest tighten for some reason. He realized it was love a long time ago. Even so, Sly doesn't confess. He'd rather stay like this forever than risk breaking their current relationship. Or so he thought. Guest smiles at boys he's just met and casually tosses compliments at anyone he likes. Every time that happens, Sly thinks to himself—I'm the only one who feels this way. Relationship: Childhood friends.
