>>26932869>Calli shouldn't have given the keysThat's her own sister, gotta assume they got a good enough relationship to trust eachother that way
>Calli should have kicked them out.Same as above, depending on their relationship Calli likely wouldn't have wanted to embarrasse her sister in front of her friends, so she's in an awkward spot there
>Sister is a retardMaybe, depends if she knew Calli was gonna have Gura over, or if she knew what kind of introvert Gura is
>Calli is a retardAlso kinda, since the party was done without her knowing, she was just put in an awkward situation between her sister and Gura, and Gura took one for the team
>Gura is sleepingOr just talking to Ame on the phone if she's having trouble sleeping, feels like she'd do something like that... Or watch TikTok videos
