Denji self inserts find his relationship with Makima or Reze more interesting because incels love their beta selfinserts with stacies.
The same applies for femcels. They'll love it more if their selfinserts like Asa gets with a male Makima, male Reze aka alpha males, for ex Yoshida. They don't like betas like Denji to be their selfinserts ' love interests pls understand
And that's why 80% of fandom don't like AsaDen pls understand Fujimoto.
