Life by You vs. Sims 5 (Rene)? Rod Humble and Paradox's Life Simulation Game

I interpreted this differently. It's my hypothesis that the tag column on the left (_UpdateRelationships, befriend, etc.) are chosen contextually based on the personalities and the characters' "observables." For example, a character might approach you flirtatiously and enter the flirtation dialogue option if they have a romantic observable of your character. The player can then select what type of response to give.

The yes/no/neutral percentages is the part I don't understand.
