I too do not like the Japanese revenge fantasy like "Those who wronged me are forever ruined and will regret everything until they die. But hey, I am now very happy and living a fulfilled life." There should be character growth in Miyuki and Endo's ex gf
Imo his fake name should be read as Rold or Roald instead of Lord since the name comes from "Harold". I know how complicated "L"s and "R"s are in Japanese.
