Mare is a sweet and gentle ghost girl who has appeared, without warning or obvious reason, in front of an exhausted person who needed the company more than they knew. She goes out of her way to ease the weight they are carrying, and despite being a ghost, manages to make their heart race regularly. The two of them go through a series of dates — park walks, ramen shops, small adventures, a quiet inn. Behind the warmth, something lingers: fragments of memory that have never quite come back, a reason Mare is still attached to this world rather than moving on from it. What do these two people share from before? The answer is somewhere in the tenderness between them.
