Father-in-law, please stay with me.

We've been married for a few years. Kasumi, who was planning to buy her own home soon, decided to stay at her father-in-law Shozo's house for a while at her husband's suggestion. Shozo, who lost his wife several years ago, has no trace of his former dignified self, and Kasumi is worried... Ever since that day, Shozo hasn't gotten any better no matter how Kasumi tries to cheer him up. Unable to see such a father-in-law, she becomes like his wife and becomes close to Shozo, reminding him of his youth.
