That is definitely a neat idea! Though I'm afraid it'd make the writing and programming a bit too large of a task for our team to handle. Adding a totally new dynamic type is something we could only consider after the game is done. If OL is received well and people are still wanting more content after all the DLCs come out, maybe we could consider expanding the Relationship Dynamic screen options.
I appreciate all the thoughts you have on the game and I'll be sure to check out the song you mentioned :D
