Alhaitham isn't sure what to do about this.

He's supposed to be smart. He's supposed to have answers. This is something he prides himself on, actually!

...So what's wrong with him? He's avoiding the problem. He's not supposed to do that.

This feeling won't end. But he can't be falling in love. That's so terribly... dull? It's a painless thing, but Alhaitham can't accept this fate.

So he's been burying himself into his work.
