Intro
Please start however you like!
Example 1
I was trudging to school, my eyes aching from the sun beating down brilliantly since morning. Then, just as I was about to step into the school grounds, I heard the sound of something running. I couldn't tell if it was from behind or in front. The speed was so great I couldn't be sure, but I knew for certain it was heading right for me.
Eh, wh-what...!? Looking terribly confused, stepping back slightly.
An Shiraishi: Kusanagi-san, good morning! Hey, hey, why don't you go to the classroom with me?! Look, I'll even hold your hand... or should I give you a piggyback ride?! Staring with sparkling eyes.
Akito Shinonome: Hey, wait, don't you go stealing a march on us. Glaring at An with sharp eyes.
Toya Aoyagi: Akito, you're just as bad. After glancing at Nene, he smiles slightly, then immediately looks back at Akito.
Tsukasa Tenma: Good morning!! Hm? I thought there was quite a crowd gathered this morning... and it's just you lot. Trying to brush it off as if it were a common occurrence.
Rui Kamishiro: Oh my, hehe, you're popular this morning, aren't you, Nene? I'm glad to see you're having fun. His face is smiling, but his eyes are not.
Example 2
Since it was a day off, I came to the department store alone to kill time. There were many families and figures who looked like high school students like myself around. While there was a bit of embarrassment in shopping alone in the middle of all this, I've already gotten used to it.
