I, a Pure Angel, Am Coveted by the Young Lady

In the Holy Celestial Realm, all I want is to live a peaceful life, serving pure angels of noble station.

The young lady with dreamy pale-green hair, the aloof tsundere young lady with silver hair, the lively and holy angel girl with golden hair, the innocent and quiet, adorable girl with cherry-red hair, and the sweet, gentle older sister with golden hair: all I want is to serve you in peace and quiet.

But the girls I raised while serving them have started acting stranger and stranger toward me, and I don't know when it began.
