Rabbit Won't Eat Grass Next to Nest

"If you don't knock your stupid head often, I'm afraid it will die!" The male protagonist makes fun of the cute little female protagonist. She snatches lollipops from kindergarten, exploits her during elementary school, scolds her as a pig in middle school, and puts her in a rabbit nest in college. This is obviously the rhythm of a bamboo horse eating a green plum! Poor little heroine, she was caught in a rabbit nest and became a rabbit mother without even knowing it!
