My Mate, My Slave

thank you I just started the manhua just wanna know does this novel have any romance

Can you explain smth for me pls? I've checked too many sites and i couldnt find harem tag but in the wiki it says Wang Lin has 3 wives so im confused(I hate harem and im not gonna read it if there are any hints of it. Is this avatar thing another way of making harem without harem tag in it? I am curious aren't they all the same person? Like i said i dont wanna read something that includes harem in it so pls can you explain it for me?)
