nyanekosensei's Manga

The story is truly heartwarming. It's about acceptance, it's about love, it's about friendship, it's about the importance of family in one's life and lastly it's about overcoming the ordeals one faces- not just imposed by the world but inner conflicts as well. I really loved the story. Although I found myself wondering about what kind of illness LiHuan has. I pray for all there is to pray to that it's not something serious. I'm also sad that he apparently forgot Yuyang's birthday and how their relationship may have lost its initial vigor but it's quite understandable. I wish someone could explain the illness part to me and if it will have a continuation or some kind of justification.
