Thank you so much!
@KiniHokulani I imagined as such, however, I'm thinking I might allow it it to add some drama. I don't like my families being perfect, and since it's too easy for relationships to progress to marriage, I want any accidental drama to became a larger deal.
Side note: I love your Forum name, I actually named my gen four heiress Hokulani (she has twin older brothers named Haku and Hani), they are all very cute (toddlers).
@ryttu3k Thank you! I'm thinking of creating a story. l play on normal life span so I tend to get my sims a job, married and moved out ASAP once they age up. However, if I take a detour and make Haven's (my gen 3 daughter, the main character of this post) third trait child of the islands, I might be able to use the spirits to guide my game and tell Haven of the truth of her father. I can feel this story becoming extremely extra. Perhaps I'll move this to the Sims 4 Stories board when I play it out.
Thank you guys so much for you replies!
