Synopsis:
Ayase Haruka stars as the title character, Amemiya Hotaru, in this adaptation of Hiura Satoru's "Hotaru no Hikari" manga series. Hotaru is a twenty-something office lady who has become a "dried fish" - she has "retired" from love, and she prefers to spend her time lazily at home. Then one day, her world gets shaken up when she unexpectedly ends up living with her boss (Naohito Fujiki). To complicate her life even further, she begins to find romance with a new employee named Makoto (Kato Kazuki).
