shaunalove doesn't mean Shauna loves Ethan, it means Ethan loves Shauna. Shauna is Ethan's best friend at the start of the game. He is with Jaime and as far as he knows, Shauna is just his best friend. He loves Jamie, he doesn't love Shauna. That is how the characters are at the start of the game. If Shauna is trans in your game, she had already transitioned before the game started. So, yes, shaunalove is false because that is how things are at the start of the game. They are friends, not lovers. That doesn't change until you decide to change your relationship with her by cheating on Jamie. The variable doesn't set to True if you stay on the loyal path, even when Jamie brings you all together. The variable is only used to track if Ethan cheated on Jamie with Shauna.
