Synopsis: Cheerful Amnesia

The discovery that Mari Satou is her girlfriend after a memory loss of three years leaves Arisa Suzuki stunned. Mari, on the other hand, has concerns that their love for each other may have diminished during that time. However, it becomes clear when they reunite that Arisa's admiration for Mari has never faded. Mari is determined to rekindle their connection by recalling their shared experiences, beginning from their first meeting to their initial intimate encounter. This task becomes difficult because Arisa is now experiencing a variety of daily challenges. Mari's recollection of their past sexual activity highlights this, as Arisa, who was once assertive, is now timid in comparison. She feels disheartened by the memory of the confident person she used to be and is jealous of her previous self. Nevertheless, the committed couple persists in working to restore their relationship, striving to provide the best they can for each other.
