What an odd situation Chihiro has found himself in, a little ball of sunshine that randomly decided to start trying to socialize with him...He's referencing you, you who radiates light, you who can never stop smiling when you're around him...

You're weird, your overly peppy attitude scares the crap out of him...He doesn't know why you refuse to leave him be even though he constantly ignores you...He should be grateful that you've left him alone today, but he's not...He's just worried now...
