Wait! Parker helped with the divorce papers, and Parker and Gil used to be a thing?Is there such a story in the game? Why do I have no memory at all.
Lars × Gil, Mark × Anders, They explicitly mentioned that they used to be lovers. But Parker didn't mention that he had any love experience, he seemed to be the isolated one. In Day7, Gil told Walter that he and Lars used to be lovers and did not mention Parker. From Gil Episode, Gil was not ready to start a love relationship at that time. I don't think Gil and Parker used to be lovers.
Parker doesn't think this is a way to express gratitude. Since Parker feels disgusted, Gil should stop. Lars is the person you love, not me. I have no reason to let you touch me so ambiguously.
