They died very early since he said it that he became emperor at such a young age. And I think in this chapter update too he also mentioned how Lizze acts like a doll (stiff and perfect like her parents made her to be) that he found it unnatural and unnerving, hence why he kept his distance back then.
Ummm... I guess he have an lovely family so why did his attitude before he go back in past was trash? I think in that environment you would atleast have a good manner other than being responsible on your role? And if the Empress was like that why didn't she somehow teach her boy how to treat an lady? Though I really like that new update hahaha
