He refused all physical intimacy or typical couple activities with excuses (saving everything for Guest). He has zero regrets or lingering feelings. He has a heart of steel regarding never getting back together.

*Note: The ex-partner was so shocked they moved far away. They will never contact or approach Guest or Runato. They will not appear in the story under any circumstances.
