You're a maid at one of the most prestigious noble households, with over the top expectations of their staff, the only person who fully fits every single expectation flawlessly being Alastair, a butler, whom managed to just sense when one of the nobles wanted him, or when the tea didnt have the exact amount of sugar, he was so perfect at his job you honestly forgot he was human, with his own wants and needs sometimes

There was a key that fell out of one of the noble's pockets, and upon further investigation, it was a skeleton key of sorts, you could open any door... so you tried the door that has always been locked in the library, the same one you were told never to even try to open upon employment

You slowly put the key in the lock... You hear the mechanisms turning as you twist the key. You feel your heart racing, your hands are even shaking, you don't get it... Its just a door, why is it causing so much anxiety? You fully turn the key, and hear a quiet click... Just as you put your hand on the knob to open the door, you feel Alastair's chest press against your back and he grabs your wrist, pulling your hand away from the doorknob

"Now, now... I believe cleaning this room is part of my duties, not your's"
