It’s the spring break of her first year of high school. Miyashiro Saya, a girl who struggled to connect with others and eventually dropped out of school, finds herself alone and without a place to belong. Her salvation comes in the form of an offer from her former teacher’s acquaintance: a job as a maid at a wealthy household. The mansion she arrives at is home to three sisters from the West. Saya, who had kept her heart closed off to the world, begins to rediscover her smile through her daily life with her new "masters." Though their personalities couldn’t be more different, their circumstances are strangely similar. This is a story of four girls, each carrying their own scars, shaping a tale of master-servant bonds and the quiet beauty of everyday life.
