Just bask in a place with fast air circulation, such as a bathroom or an air-conditioned room. Or take it to dry cleaning.

Or find a friend who lives in a high place and see if he can get some sun.

Actually, about trust, I think you are a little paranoid about being killed. People who live together don't need to get into trouble with each other. The key is not to let your own affairs interfere with each other. To give convenience to others is to give convenience to yourself. If you can handle it well and everyone is comfortable, no one will bother you. For example, you can post some slogans and intimate tips.
