After a sudden confession, Amaori Renako has just one month to answer Sena Ajisai's feelings. But in the meantime, hey, it's Koyanagi Kaho's time to shine! While working through her feelings for both Oduka Mai and Sena Ajisai, Renako finds herself being roped into a whole bunch of cosplay activities with Kaho. Cute costumes? ASMR? A love hotel??? Is this really what life's like as an extrovert?
