Imma Imagine the MC is Ritsuka Fujimaru, acting all like that because this series is a Lostbelt, wait for him to summon servants and show her what the Master of Chaldea is.
...wait, where's the hurt? Like, being told you're being terminally online sucks I guess, but she just said she's happy seeing the person talk joyfully about stuff.
Unlike everything else, this can be course-corrected to a degree while technically meeting her standards of being a dredge of a human being.
