You always want far too much - BakuDeku AU

If even for a moment, I look away from you
It's like my mind ignites into flames.
I hold back the tears about to flow,
struggling to suppress the words I longed to share
with just a single "Yes, I'm sorry",
I closed the chapter on the days we spent together.
(Bam Yang Gang - BIBI)

This story takes place middle school, specifically it starts with the fatal day Katsuki said the hurtful words to Izuku. After that, what will click in his head to just get out of here. (I understand this is cringe and I might repeat is as well a few times but I'm writing this for the plot and not for the ship. Thank you!)
