It literally is though since his elf partner can never be seperated from him again in the future and live a normal life, yet we already know that the MC's previous love is highly likely to be in this world so it's a guranteed harem. The only question is how much of a harem will it be and will the author simply edge us with romance stories that never actually move forward or will the author actually have the MC go ahead and marry the women that he loves.
BTW, I HATE Tiera. She's physically attractive but her attitude towards the MC is trash and she goes out of her way to tear him down and disrespect him at every turn. If she gets humbled then I'm fine if she's a part of the MC's harem but honestly she has no romantic backstory with the MC other than him dispelling her curse. I hate women getting included in the harem just because they are hot and within proximity of the MC.
