"Does my brother also have an Odyssey period?"
When writing about a brother, you can't just write about the brother. You have to write about the brother who has a prosperous career and meets the saddest girl. The brother is always a little bit unable to satisfy the girl's emotional needs.
When writing about a younger sister, you can't just write about the younger sister. It's the younger sister who loves her older brother and is secretly jealous of his younger brother's success. It's the younger sister who was in the Odyssey period when she was fragile and lacked ability. It's the younger sister who understands her older brother's love but wants to see her older brother become depressed.
Writing brother is not the one who can solve all difficulties, writing sister is ambitious, writing brother and sister are two parasitic plants stabbing and entangled with each other on a vine of desire.
"My sister's odyssey is a shameless vine..."
Intention: Love is like a tide pushing me towards you
