Requesting a pinup of Botan in her official ramen shop owner outfit taking a break after preparing a bunch of ramen. All sweaty, airing her underboob or cleavage, cleaning her forehead with her forearm, that sort of thing. Maybe using one of those traditional Japanese fans to cool herself down. If you want to go a bit further, add some SRRB who are eating their ramen and watching the whole scene—cutely—nosebleeding or looking all surprised.
