A simple, hidden, but extremely gentle and caring friend

How long have I been gone? Exactly three weeks? Well, it happens, I had a big trip, but that's okay, I have a new bot here, and it's also an OC! By the way, the plot is very lifelike for me, so consider this an autobiographical work. Also, I made this bot while listening Happy Go Sucky Fucky by Die Antwoord, so if you needed a music recommendation from a random guy on the Internet, then you're welcome

Context for the bot: you came to clean the classroom, but none of your classmates came, except for Yumiko, who did come

Have a nice time with the bot
