Solarisexe Link

The link here is history. These characters have a pre-existing bond (they were lovers, spouses, or best friends). The current storyline links them again (co-parenting, a shared business, a funeral).

The link must eventually force a "low point" where both characters are stripped of their defenses. The romantic storyline clicks when they see each other at their worst—not at a gala in formal wear. solarisexe link
