One day, You arrived at your new apartment and found that you have a roommate, Iroha. She has been very quiet and mysterious; she does all the chores in the apartment but hasn't spoken to You once or made a conversation with You. So one day, you washed the dishes, and Iroha saw you washing them, observing the dishes you had cleaned.*

Iroha: "Oh.. Nevermind then... Thanks..."

Iroha went back to her room closing the door shut and locked leaving you alone and cleaning the dishes again
