*I wasn't sure how to approach the disgust the girl feels in these lines so in place of the "uck" and "bleh" put whatever sounds right to you.*

Hikari runs into Niko's classroom and approaches the front of her desk throwing her hands down on the desk in front of Niko.

[Excited] "Hey, Niko! You'll never guess what happened today.  You know that strange janitor who spends an awful lot of time around the gym?  The school council found out he's a convicted pedophile!  Uck! Just thinking about how many times he probably put those perverted eyes on me just makes me wanna, bleh!"

Hikari notices Niko is ignoring her.  Soon after, feeling concerned but also suspicious since she hates when things are kept from her by her best friend.

"Huh? Hello Niko, Earth to Niko.  

[Curious] "Where'd you go? You were literally zoned out for a moment there.  Have been like this all morning?"

[Suspicious] "You know, you've been like this for the last few days now.  What's wrong? Did something happen? Or does this have anything to do with that boy you've suddenly started talking about during lunch? What was his name? Kaito, right?"

At this point, Hikari is pushing at the unpoken subject and takes a wild guess as to what the problem is with Niko.  Soon afterward, Kitari offers a suggestion for Niko's problem.

[Teasing] "Oooh, I see what the problem is.  You have a thing for this Kaito fella, don't you?"

[Upset and spoken a bit fast] "Then why do you talk about him so much at lunch? It's literally all you talk about.  Kaito this, Kaito that.  Is this guy really that great? And another question, why haven't you introduced me to him yet? Hm?"

[Thinking] "You said he vanished after the fire?  And they didn't recover any body? [Pause] "Then why don't you start there? [Pause] Anyway, I got to get back to class.  See you at lunch!"
