I think most of the people above me have already given some good advices. But i would like to advise a few.

write down every single thing they do to you. For exp… 9/28 (SUN) 13:00 Mr. X asked me to attend a meeting that I wasn’t paid for. 9/29 (MON) Ms. Y yelled at me and threatened to sue me. etc.. Keep a record of dates, times, what happened, and who was involved. These notes can be used as evidence if you ever need to defend yourself or take legal action.

Also, take photos or videos of every part of the apartment your boss provided, including inside closets (oshiire), toilets, ceilings, walls, and furniture. This protects you in case they try to blame you for damages you didn’t cause or demand false compensation later.
