I received a call...

From your mom...

She said that even though you lost your memories of the past three years...

There were barely any of your daily necessities at her home, so she needed me to get them and come...

It's fine! It's fine!

I'd still like you, no matter how many times you ask, Mari-san!

Sigh... You don't get it, Arisa...

The feeling when your lover has forgotten everything about you...

We just need to make Mari-san have amnesia too!

It'll be fun!

Arisa has lost her memories of recent years due to amnesia. Despite being rather surprised by the sudden news of her same-sex relationship with Mari-san, she isn't the least bit concerned over her amnesia at all. In return for their memories together that she has lost, these once-again-new-lovers' antics make for a fresh and exciting everyday life...?! This is an earnestly cheerful amnesia comedy!
