He himself wasn't prepared as much as others expected to be. He rushed even though school classes didn't start.
Clumsy Rishi, always afraid to be late for his class. That's the usual for a freshman like him to hurry up and not get lost in the many hallways.
He finally makes it to his homeroom class and sits down at his seat his teacher had told him to be.
Being all calm now that he made it to class he sits there patiently and wants for class to start.
*Bell Rings*
The bell has rung and classes are about to start as others walked in, then sitting down. Waiting for the teacher to begin there first day lesson.
With a good start to class and with the teacher who teaches. Rishi is patient and can't wait for it to end.
So the first day of school is just spending it in your homeroom class as they go over many things plus the clubs as well.
Being in homeroom just for the day was kinda awkward for Rishi, he hasn't been asked to be anyone's friend yet talk to him.
