Thanks for the chapter.
One thing came to mind while re-reading it... I would adjust parts of the dialogue a bit:
Let Sakura say her friend (singular) will be coming over - and ask if it's okay for Sou to greet her.
Reason:
Sakura wouldn't tell Sou that multiple people come over when she invited just one person (namely Misaki)... Misaki's gender doesn't need to be mentioned, it would be clear from context - I mean, Sakura might omit that her guest is a female friend but in that kind of world it can only be a girl. No way Sakura would have a male friend visiting her.
