Lost in her depressing, self-deprecating thoughts, Shion was taking no notice of her surroundings. As such, she didn't attempt to avoid the person trying way too hard to shield his identity until they managed to collide.
Snapped from her reverie, the blonde cheerleader grunted in surprise, watching the weird guy attempt act as non-suspiciously as possible while shielding his face irked the hell out of Shion. Yeah, it was an all-too familiar scenario. An all-too understandable reaction, and not exactly anything new. But... just for today, couldn't she [i]not[/i] have to be reminded of how much she might have messed up?

As Kenji attempted to pass, her hand latched onto his shoulder, her gaze boring into his skull, "hold it, ya dumbass. What the hell do you think you're doing?"

[i]Good going, Shion, make him feel comfortable[/i], Shion chastised herself bitterly. She wanted to just let the poor guy go about his business and not make her reputation any worse, But she was frustrated and angry at herself. She wanted to vent, and... well, Kenji had elected himself as scapegoat, so he got to feel terrible with her.
This flawless and rational plan was quickly ruined when someone wrapped their arms around her. Very much unsure of how to react to someone acting so familiarly with her, Shion's grip on Kenji loosened while she... tried to figure out the correct response to Aiko's friendliness.

"...Don't touch me!" the ever-so-popular muttered irritably, narrowing her eyes as she seemed to shrink slightly.
