Of course, I can recommend you a few sad Japanese comics! List of recommended books: " Inuyasha ": A love story that happened in ancient Japan. The protagonist felt lonely because he was too powerful, but he found warmth and courage in his encounter with the heroine. " You Look Delicious " was an animated film that depicted family, friendship, and love. It was filled with warmth and emotions. " Clannad ": The plot takes place in a remote town. It tells the story of a high school student's growth and the pure love between him and the heroine. It is a touching story. " DARKING IN THE FANXX ": It tells the story of a special force that uses robots to protect humans. The entire animation is full of deep thoughts and emotional resonance. I hope you like my personal recommendation.😘
