[Sousei is quiet again, listening, and... well, it's hard to listen to, admittedly. It's hard to hear Tenka talk about something that pained him that much, so nonchalantly. His eyes narrow, both at the slap of Tenka's hand, and at his words, and he repeats himself--]

Painlessly.

This cannot be the only medical advancement of this place. [There must be anesthesia, better than what they had back home. There must be ways to make sure Tenka isn't conscious for it, without smacking him over the head.

There must be something.]

I am not satisfied with settling for a subpar option. [Not when it comes to Tenka's health and well-being. He wants to solve this too. But not if it means Tenka will have even more nightmares in the future.]
