Oh man, loneliness and the feeling of loss are doing a number on me. Based on your description, maybe it's not safe for me to read this one. On the other hand, I'm a sucker for cute pandas/bears so I'm interested. I don't mind stories with hardships and characters who go through it as long as the resolution doesn't crush my heart.
Without spoilers, do you think it's okay for me to read it when it comes out ?
