My parents' place is on a very high hill...

So I don't really know how to ride a bicycle...

Eeeh? You could have told me...

We could have just walked...

No...

I just thought you'd be happy, Arisa... Since you were saying you wanted a bicycle date...

The summary so far: 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!
