Yi Sui, the beloved youngest daughter of the Yi family, suffers from congenital heart disease and has been soft-tempered since she was a child. She also has a childhood sweetheart, Yan Yu, who she grew up with and is one year older than her.
Yan Yu, the only son of the Yan family, was raised by his family since he was a child. Although he appears to be humble and courteous towards his superiors, he is actually cold-tempered and treats everyone else the same. Only Yi Sui is protected and taken care of, showing another side of herself.
For Yi Sui, apart from family members, brother Yan Yu is the best to her. He protects her at school, goes to and from school with her, and cares about her physical condition at all times. So when she learned that her family had arranged a baby wedding for her and brother Yan Yu, Yi Sui was filled with joy.
Unexpectedly, after Yan Yu withdrew from a mathematics competition because of Yi Sui, Yi Sui only learned about it from other people's mouths.
"Isn't Yi Sui a drag on Yan Yu? She probably won't live long with her illness."
"Don't go too far. At least Yan Yu regards her as his responsibility."
That night, Yi Sui, who had fled, encountered a car accident on the road. In the end, Yan Yu only got the news that the Yi family was going abroad and Yi Sui was studying in the north.
After several years of separation, Yan's elders became seriously ill, so they renewed their engagement on the pretext of happiness.
When Yi Sui returned home, her whole personality changed drastically. The little girl who was protected behind her has long been on her own, and the dependence she had in the past no longer exists.
Yan Yu couldn't admit that Yi Sui's life had already been filled with another name. He was furious with jealousy, but there was nothing he could do.
After the marriage, when Yan Yu faced Yi Sui's indifference again, he held her chin and faced him, saying in a begging tone, "Suisui, we are married."
Yi Sui looked directly at him with red eyes and said, "But isn't this a responsibility?"
The "ear" of Yi Sui is also "year". Like the ear of rice, it will achieve perfect fruit and be safe every year. But one day, Yi Sui recalled her life and couldn't help but sigh - it must be a curse.
