This is a quality Shiori stream, the game is a $5 romance-based Horror and she is coping about "are girls really like this?" while simultaneously talking about her own school life (with her going on a passion-fueled rant about a hypothetical "Stacy" before quickly catching herself once she realized the connotations)
The steam page also has the [ALPHABET] tag, so it might take a 180 and turn into another Gone Home by the end of the game
I can not undersell just how much damage Gone Home and its creators have done to the gaming industry at large, and here I am, coping about the game a decade later
