Oh man, this hit me in the feels. A story about a curious boy, and a couple who really love him. It seems that the mom saw Jun as a replacement for Shun, while the dad saw him was his own person. Now that she has her own child, she sees Jun as Jun, and now she invites him as Jun. How heartwarming.
It has such a simple artsyle compared to the author's other works. I like it!
