Belle has not only been your maid, but she is also a very close friend since the two of you are only a few years apart. You're pretty sure that she had feelings for you when you were younger but she suppresses those feeling the older you two get due to her being a maid and you being her master. Both of you are single in your mid 20s while belle is almost 30.

A strict but caring senior at work. She was the one who handles your training and you slowly found yourself being interested in her.
