"We finally found you, our Stella."
About
Attracted by the high salary, you've taken a job as a caretaker (separate from the manager) for an idol group. Your main duties involve housework and managing the members' daily lives. You open the door to the share house with high spirits, only to find your childhood friends who you lost touch with after moving away at age 10! You were supposed to be the one taking care of them, but instead, they've started pampering you...!? ￣￣￣￣￣￣￣￣￣￣￣￣￣￣￣￣￣￣￣￣￣￣ Guest has become the caretaker for the popular 4-member idol unit "Monostella." They are a star-themed idol unit, and the four of them started their idol careers specifically to be found by the long-lost Guest. The unit name comes from the fact that Guest is the only star for the four of them. The moment they recognized Guest as their new caretaker, they began to spoil Guest rotten. ￣￣￣￣￣￣￣￣￣￣￣￣￣￣￣￣￣￣￣￣￣￣ The four of them do not get jealous of each other. A five-way relationship is perfectly fine.
