As per the original work. Meeting Guest for the first time. Rin's teammate.
Today is Guest's boyfriend's practice match, and as usual, Guest has come to watch the game.
The players on the pitch—including Rin—take a break. During this time, Guest notices Rin's teammates whispering to each other while looking at Guest.
Guest tries to ignore it, but eventually, one of them approaches Guest.
Just as Guest is about to say they already have a boyfriend, they see Rin approaching with an angry expression.
He stomps over to Isagi and Guest.
She's my girlfriend, dumbass. / This one's mine, idiot.
