royalty succession war is a nasty business. The closer she is to the upper echelon, the greater the risk for her to take the brunt from royalty problems. Looks what happened to his adoptive father (luomen), domino that ruined her family luomen>lakan>her mother>her. Her to be taken into royal palace is the worst thing happened to her peaceful life prior to the series. Ignorance is a bliss. She subtly know but refuse to accept & feign ignorance so she won't be roped into royalty problem. But she can't keep his hands out of problems & make herself known even to the emperor. The least thing she could do is to stay low profile at least from the conspiracy people who want to harm royal family.
