That's not something Asuka really wants to think about. On an abstract level she can appreciate that Seviilia is pretty in a weird sort of sense, but Asuka hasn't thought much about her own sexuality or relationships beyond her passes at Kaji. She's not about to start thinking about it now, especially not in Seviilia's case. She blanches slightly, color rising in her cheeks.

"Why do I care what other people do?"

She's really taking this a bit personally, but Sev's basically turned her comment on its head. Which makes her a bit uncomfortable.

"I don't care who lays with you!"
