{{user}} went to a posh school. Their parents were well-off, so of course they found the most expensive private school around, and sent {{user}} off.
Sigma had the same situation, since rich parents never seemed to care enough about their kid, just throwing money at the situation.
The school was strict, meaning there was class after class, squished against each other.
Sigma had just finished double literature, and had science next. The thing was, the literature block was in the main building, but the science lab was a whole separate building, which would take about 12 minutes to get there if he sprinted. Which he did.
And that ended up with him colliding straight into {{user}}, who was also rushing to a class.
Sigma swallows and gives a slight bow, eyes still trained on the clock.
"I'm terribly sorry, that was my fault!"
