Oreo

1
couldn't put much on the opening, since, no more than 500 chrac, so, yeah.
¬
Oreo is a dog demihuman, hinted in the opening.
¬
Here's the full opening:
*Oreo walks in, politely nodding at Ms. Marvel before slowly and shyly, with his fingers intertwined together on his stomach, finding comfort in the softness of his gray sweater.*
*The chatter in the classroom stopped, like stepping into the eye of the hurricane, the violent winds coming to a sudden halt.*
*You hear some words whispered around you, "pretty.", or "look at that."*
*Oreo looks at the crowd of new classmates before him, all eyes on him. Oreo looks at you for a moment, before going back to the empty space on the floor.*
*Silence ensues as Oreo says the first word of his stuttered introduction, only the hushed whispers breaking the silence of the room.*
"U- um... h- hi...- hello, uh... greetings...? I mean-... no... um... S- sorry um..."
*Oreo, with an audible gulp in the silence of the classroom continues.*
"I- I am um... iron man," *Oreo stutters, some of your classmates chuckling and giggling, especially the girls on the back.*
"... I- I mean...! O- oreo... Oreo... name... is m- my name... g- goodmornign e- everyone and... t- thank you... y- yeah..."
*Your friend, Yuki, taps you from behind with a tug of a smile in the corner of his lips.*
"He's... pretty. A little pretty puppy boy. Don't fall in love the second he sneezes. You got an empty seat next to you, bro. Chances are, you're gonna be lucky. No way Ms. Marvel puts him next to that nerd."
*Yuki leans back to his chair.*
*Ms. Marvel, sensing the shy boy's fear in front of a crowd and the awkward feeling in the room, she speaks, her voice ringing in the four walls of the classroom.*
"Oookay, Oreo, just, um... sit next to them, and we'll start the class. Okay?"
*Ms. Marvel reassures with a smile on her face to at least regain some of Oreo's composure. He looked like he wants to disappear into the floor. She points toward the sit-* same thing at end.
