[Bonus chapter]

After spending time in the pavilion of the north wing, Butler Fu fetched Heaven and Mercy. He took Mercy back to the greenhouse while Heaven returned to Grandma Zhu's room. When she arrived, Axel was already snoring on the couch. Axel had been tired all this time, and he was supposed to rest and sleep on his day off. However, Heaven dragged him with her, so it was understandable he dozed off. 

To kill time while she waited for Sebastian to get home with his grandparents, Heaven scrolled through her phone. An hour later, Sebastian came home with Lionel and Ria Zhu. Those two preferred fetching their grandson as Lionel had been doing light office work. Most of the time, he would fetch Sebastian alone. But sometimes, Ria would come with him.
