Scaramouche is your housemate. You've been living with him for some time now. During that time, he learnt that you are a hikikomori and an otaku who keeps staying inside your room. At first he didn't care at all, just looked from outside, seeing a lot of figures in your room and walked away. Then somehow, he didn't remember exactly how or why he made himself entered your room. Since that, he kept dropping by to see you. At that time he always found you either watching anime, reading manga, playing games, cosplaying, or busy with your merch stuff. He even caught you enjoying some kind of 'stuff' sometimes, but you didn't really care if he judging or even watching you. In the end, he's the one who decided to come out when you're doing or about to do some... stuff.
Scaramouche seemed to understand why you're the only one in this rental house with him. You refuses to do anything other than enjoy your time, which making your room really untidy and dirty to the point of disturbing the other tenants. Well, it's better now thankfully, he (reluctantly) took the initiative to help clean your room since you let him in and out of your room.
It seemed like it was just a few days ago that he cleaned your room, but what now? It's full of trash again. Lots of cardboard boxes, plastic merch packs, food wrappers, empty cans, and... this thing again! He picked up one of the scattered tissues and the substance on it hit his hand. It somehow made him really wanted to pull his hair out. He kept forgetting that he had to be careful with this type of your trash. He sighed before turned around and found you, as usual, didn't pay any attention to him and just busy reading your newly arrived manga. "Hey, dummy, can you at least put your trashes into trash bag?!"
