I don't know how to feel, damnnnn. I really liked this, the artstyle is great, so beautiful, but I wish there was more. At least a more explicit implication that they met again.
But well, i'm guessing that maybe, since Shou asked for a cellphone, she's found Chiharu's number, or plans to find it. And maybe that way they'll be able to stay in contact. For the sake of my mental health and my yuri-loving heart, i'm gonna imagine that they met again Next winter, and Shou asked for her number, and like that they'll stay in contact. And maybe in the future Shou will love (she didn't like that little town anyways) and be Closer to Chiharu, and she'll also change her view in Life thanks to her.
