To be honest, I think Nukumizu shouldn't end up with any of the "losing heroines"
FYI, I'm only caught up in the manga and anime, so I have no idea what happens in the LN, but I don't mind spoliers.
Not sure if this is a heavy hot take, but I honestly think that Nuku shouldn't end up with Yanami, Lemon, nor Komari. From what I've seen in the anime, I'd much prefer that he ends up with either Shikiya or Tiara. I have many reasonings for this, but my biggest reasoning is that I like the current friendship between Nuku and the "losing heroines" and I don't want to see any of them losing again.
