Your first line is too long, you probably lost a few readers there. No need for the "for a while" at the beginning. And separating the rest into two, or more, sentences would be better imo.
"Fairlight University was bustling with life."
This sentence sounds like a first line, doesn't tie well to the previous paragraph. I would recommend starting here and adding the part about Ryvan standing motionless as the second paragraph. Also, the first line doesn't specify whether Ryvan is standing or lying down so I assumed he was lying down on a bed. You can imagine my confusion when the university came into play.
I love the image you evoked with the university. Would love to study at a place like that!
I had to look up what umber means, though I think I'm in the minority here. English isn't something I use in daily life, after all.
Flawless skin is boring. Maybe adding a scar from childhood or a freckle would make him sound more interesting.
Oh, no. He has a fiancee. I smell trouble as this is a BL.
"Only a small push"? I thought the doors were heavy? Also how does "just being excited" look like? Don't leave it to the reader, make us imagine what you have in mind.
And I think that's all I have for the first episode. Good job!
