Hitori de Ikiru wa Mamanaranu

Shuuko Maeda, 28, single, boyfriendless and ordinary at work, lives in a shared house with her unique friends. Eika Matsuki, a career woman who lives for work, Misaki Kawaseda, a singer who sings and talks about love, and Shio Momoyama, a laid-back person who freelances both at work and in her private life. They can overcome the daily fatigue and stress by drinking together.

"As long as you're having fun now, that's all that matters." Shuuko went about her daily life thinking that, but then realized that she was about to turn 30. The environment surrounding Shuuko and her friends gradually changes... Still they are nearing the "Arasa" age group...
"Is it okay for me to just live my life as it is?"
