When Fuku returned home during the holidays, his sister-in-law Kasumi, a former honor student who worked for a large company, had remained withdrawn since she became mentally ill due to overwork. His family recommends treatment, but Fuku feels broken by forcing himself to act. One day, she suddenly says, "I can't do anything, I'm sorry for being such a sister-in-law."
