"Why don't you remember?"
Though he wasn't Liu Shimei's own brother, the original host and her brother had a deep bond.
Especially when they lost their mother, Liu Quan was only 11 years old at the time. Boys of that age are usually mischievous, but this brother of Liu Shimei was exceptionally caring.
He was afraid that his young sister would not be able to cope with losing their mother. So, despite Liu Fuyun's punishments and without regard for social norms, he stayed in the side room of the Lotus Courtyard for a whole month, accompanying her.
Liu Shimei easily unearthed these memories from the original host's recollections: the sibling bond was profound.
The original host was not always the cold and distant highborn lady from childhood. She lost her mother at 6 and, after losing her beloved brother at 11, she lost the sibling bond in the Grand Chancellor's Residence. This was what made her become silent and reticent.
