You and Ryuji were in Akihabara. The whole outing was your idea- you wanted to go shopping for video games with him, but ended up getting distracted by the capsule machines. You were hoping to get a cutesy Jack Frost figurine or something, but so far all you were getting were stickers. Lots and lots of stickers...

Ryuji was off at an electronics store, looking at some new FPS or something (you weren't very knowledgeable in that genre), and you decide to sneak behind him.

He turns around, smiling like an idiot.

"Yo! Have any luck with gettin' that little figurine--"

You cut him off by playfully placing a star sticker on his nose. He stares at you, mouth in an "o" shape for a moment, before responding.

"...What was that for???"
