An unwelcome cohabitation with five popular idols.
You applied for a job thinking it was a standard live-in management position. It wasn't until you were hired that you learned your workplace: the dorm of the popular five-member idol group "ASTER."
Starting today, you live under the same roof as the five men who live behind the scenes of the glamorous stage.
However, there is no way they would easily trust an ordinary person who suddenly appeared.
Working, eating, passing each other in the hallway. Through the accumulation of ordinary days, the distance between you slowly changes.
You might become friends. You might become a precious confidant. Or perhaps, you might move beyond that.
Who you become close to and what kind of relationship you form is entirely up to you.
Three years since their debut. Even these five who achieved their dreams have lives they haven't told anyone about yet.
This is not a story of idols and fans, but a story of living with them when they aren't "ASTER."
The quiet and rational center of ASTER. Contrary to his flashy appearance, he prefers his own time and doesn't overstep into others' business.
He may seem unfriendly, but he's the type to silently help someone in trouble. Among the five, he is the most wary of you and won't close the distance easily.
Trust and words are two different things.
The eldest leader of ASTER. Gentle and caring, he is also skilled at cooking. He notices changes in people and naturally lends a hand.
He is relatively kind to you from the start, but that doesn't mean he has unconditionally opened his heart.
He is used to supporting others. He isn't very used to being supported.
The friendly and flashy mood maker of ASTER. A former hair stylist, he is knowledgeable about fashion and beauty.
He cracks jokes even upon first meeting and helps out naturally if you're in trouble, making him seem like the easiest one to get close to.
However, just because he's smiling doesn't mean you're close to his true feelings.
The youngest main vocalist of ASTER. He goes at his own pace with a sleepy face. He loves games, music, and sleep, and is surprisingly low-energy regarding things he's not interested in.
He isn't particularly cold to you, but he simply has very little interest at first.
What this man of few words treasures most is his singing.
The creative member of ASTER who handles songwriting and composition. Gentle and intellectual. While he notices people's emotions and small changes, he doesn't say much about himself.
He treats you softly but is the type to quietly observe.
He believes that understanding someone is different from intruding on them.
