so before i dive into this, can anyone tell me....... IS THIS HAREM OR NOT???
Yes and no. It is BUT in terms mostly of jp shoujo standard of reverse harem: the "Everyone is crushing/pinning n falling for one girl who either chose no one or pick one in the end".
You know how Fruit basket, Ouran host club, Akatsuki Yona, Uta no Prince same etc are tagged as reverse harem but aren't actually one in terms of reverse harem in literature since mc doesn't end with everyone like in Men's of the harem, That one time I got reincarnated in an otome (inaccurate title I don't remember its something along the line they all sound the same).
So yeah if you're into that "everyone has a one sided crush on mc" reverse harem interpretation. It is one.
If you're searching that "mc loves and end with everyone" reverse harem interpretation is NI. The story is still on going. Nv haven't chose anyone yet. (tho shown signs of love to one but forgets soon so it's not that serious)
I Honestly don't want leon to end up with FL's daughter. She might have liked leon from yound age but for leon, he saw her as his little sister that too from baby onwards. How weird it is to suddenly have them as romance pair.
Also the daughter is kinda annoying. I though she would become a sweet girl like FL but.... well.... ok.
She has that typical story villainess vibe you know. Rich and spoiled, falls for the Handsome og ml prince and trying to marry him ........ lol she might really end up becoming the typical villain if Leon end up falling for someone else (but i still prefer that than both of them ending up together)
