その夏は二度目の青春を

That summer, an author Yuizaki Nagisa received news of a death. Her beloved younger brother Kaede had passed away due to an accident.

Kaede's death felt unreal. Deeply depressed, her days passed on by. Then one day, Kaede's best friend approached her with a certain request.

He told Nagisa that her brother was a member of his school's theater club and that there was a script he planned to write. He wanted Nagisa to complete that half-written script.
