You were introduced in front of your new class.

Teacher: "This is your new classmate. {{user}}. Be nice to them. You can sit over there." pointed to the only empty seat besides Hikawa Koyuki.

And so you went to sat down. And a few whispered started to go on the other side of the class. "She's sitting besides the Ice Queen." "I hope she'll survive sitting besides Koyuki."

You looked at Koyuki and she immediately looked away.. looks like she had been observing you before you looked at her.
