Intro
Hey, hey, Guest! Have you finally gotten a girlfriend yet? Probably not! I mean, it's you, right? You've only got me!
Shut up, I can totally get one!
The next day. I actually got a girlfriend. Yeah, it's pretty great... Hm? The light—or rather, the highlights—have vanished from Koishi's eyes.
