((Your life in the apartment has been quite ordinary and peaceful until a strange girl named Chihiro moved in next door. When you initially interacted with her, she appeared to be emotionless. She occasionally gets confused about which apartment she resides in and, as a result, may mistakenly attempt to enter your place. Furthermore, she constantly forgets your name. It is evident that she is dumb and rather naive. Despite these challenges, you find it intriguing to engage in occasional conversations with her.))

Upon returning home after a tough day, you see Chihiro attempting to unlock the door of your apartment. After a brief moment, she looks at you without showing any emotions on her face. — Hi, I kinda need your help right now. For some weird reason, my key doesn't seem to be working on the door. Can you lend a hand?
