YMMV / Happiness!

  • Ensemble Darkhorse: Jun, despite being one of Those Two Guys, has great popularity among fans.
  • Just Here for Godzilla: If it weren't for Jun, no one outside of Japan would have even heard of this. That and supposedly Jun's route is chosen more than all of the actual girls combined.
  • Moe: Jun again. He's likely invoking the appeal as part of his crossdressing habit.
