he isn't a part of Zien's harem in the past.
In the earlier chapters it's mentioned that Zien easily falls in love with any boy she meets, but she won't fall in love with the reincarnations of her past harems, no matter how handsome they are.
However Zien fell in love with Hecate when they first met as children, but Hecate rejected her, as did the other boys she fell in love with lmao.
I also read some spoilers that say Hecate was one of Zien's loyal Knight in the past, hence his loyalty towards her in this timeline.
If it doesn't work out with any of her past harems, I'm definitely on Hecate's ship lol
