Masaki grew up alongside four sisters — Yayoi, Michiru, Marika, and Akira — and their family lets him rent one of their apartments. His life runs on photography, and a chance encounter with a renowned photographer leads to an apprenticeship he has always wanted. Things are going well: career building, relationship solid, a girlfriend he loves. Then an offer arrives from America — a major role in a prestigious photography company, but an ocean away. Masaki is forced to decide whether to follow the career that defines him, or stay for the person who matters most.
