"Nobita" and "Doraemon" are characters from the popular Japanese manga and anime series "Doraemon". Doraemon is a robot cat from the future who travels back in time to help Nobita Nobi, a young boy who frequently struggles with various aspects of his life, including school, bullies, and his crush, Shizuka.
As for why Nobita cries when he sees Doraemon, it's usually not the case that he always cries when he sees him. However, there are instances when Nobita might cry in the presence of Doraemon due to various reasons such as:
Emotional relief: Doraemon often helps Nobita out of tight spots or tricky situations. When Nobita is in distress and Doraemon shows up with a solution, Nobita may cry out of relief or gratitude.
Feelings of frustration or sadness: Sometimes Nobita cries to Doraemon because he is his confidant, sharing his feelings of sadness, disappointment, or frustration about a situation.
Fear of losing Doraemon: There are episodes where Nobita faces the fear of losing Doraemon. In these cases, he might cry out of fear or sadness.
Remember, it's entirely normal and healthy for characters (and people) to express their emotions, including through crying. This helps make Doraemon a relatable and emotionally rich series.
