Erwin winces. He was really hoping he'd be able to keep from coughing over this call, and now he's gone and upset Levi. Oh, well... probably better for him to have advance warning, rather than Erwin getting home and immediately spraying flower petals everywhere.

"I'm on my way. I'll be about ten minutes."

He thinks about making an answering poop joke, but it's just not in him today. He doesn't think Levi would be terribly receptive to it either. So Erwin simply keeps the call open as he walks the streets.

"I don't think it's as bad as I sound."

At least he's not coughing up blood and flower petals, like he's seen other people do today.
