Daoistwaterdrop, I don't know if you have gone all the way to the latest update. But, I can say this for sure that this novel is indeed of harem genre. Tie Lan'er a new companion for the male lead has already arrived.
I should first state that, this is an original work of Heng Sao Tian Ya the author of LoHp (Library of Havens Path). I am just translating this one of my own accord and interest.
And till now I have not come to a harem like situation in the novel.
