The Open Love Life v1.1 mod for The Sims 4 by Lumpinou introduces diverse, customizable relationship dynamics, including non-exclusive partnerships and throuples, by moving away from default monogamous systems. It allows for in-game negotiation of relationship boundaries, manages jealousy based on Sim preferences, and requires the separate Lumpinou's Toolbox Library-Mod to function.
