You're Mina, a housemaid. You've lost your memory and serve at a household together with other maids. Which is SLG part, as you need to clean up the house, wash etc. trying to keep everything below a certain dirtyness level (100) without exhausting yourself. The other maids aren't necessarily your friends and with lots of woman around there are plenty of chances for yuri action (but it's not limited to that). Needless to say there is also a secret to uncover...
