The show doesn't build to heartbreak, it lives inside it the whole time, and every soft moment with Isla is borrowed time you're spending knowing exactly how it ends. You're not watching a story about androids; you're watching someone say goodbye to a person, over thirteen episodes, one quiet conversation at a time. The tonal whiplash between comedy and devastation will destroy half the people who watch it. The other half will never forget it.

In a near future where androids have become part of everyday life, SA Corporation manufactures Giftia: synthetic beings so emotionally sophisticated they're nearly indistinguishable from humans. There's one catch. Each Giftia has a limited service life, and once it runs out they lose their memories and can become hostile. To deal with this, SA Corporation runs a terminal service that collects Giftias whose time has expired. Tsukasa Mizugaki, a newly hired employee, joins this service and is teamed with Isla, a veteran Giftia known for her skill at retrievals. As they work together to bring in other androids, Tsukasa must come to terms with his feelings for Isla before her own time is up.
