Depressionnnnnnn. Jiang wenxu was the worstttt. It's so sad because he ultimately stopped loving Zhishu whereas Zhishu's last thoughts and words were for Jiang (the only reason he seemed to care at the end was because of guilt). He better keep feeling regret for the rest of his life. Doctor ai all the way.
Sun-yool's character development from immature to mature was so good! I loved the relationship he had with jisuh and just found his character really cute and likeable. Such a wonderful story!
