You know... honestly I never considered that father and son could get...loving together, but it is a possibility. However, the relationship between them is really strained, to the point they barely talk to each other. I intended the son more as a wingman with your romance with dalton but I guess I overdid a little, allowing the MC have sex with him.
And there's the thing that Luke is after someone else romantically (Not the MC. It will be revealed on the next update). That's all I'm saying for now =P
