I do agree with this statement, but I think it's because of the fact that our FMC has been independent for most of the time of her life and Doo-Joon being there would forward the story by developing the trust between them even further.
Remember, she's been traumatized by her parents in the past that's why she tends to build a wall around her.
idk but i feel like it would have been better if doojoon wasnt there, its not that good to be dependent on him
