With the patch, yes. Go for the forbidden or harem route to get the younger daughter.
I just hope this alteration Lux mentions at the end of this build won't mess with the logic behind Emily's apprehension. There are several reasons Emily is so against Ada getting some love. 1. Because she is the MC's daughter, which is wrong in itself to her. 2. She is underage, Emily even thinks Ada knows nothing of sex until corrected by Ada herself because Ada is so young. That second bit won't work if Ada's age is raised, especially not the lack of sexual knowledge Emily thinks her younger daughter has. I mean, come on, do you really expect a person to not know at least basic sexual knowledge by age 18? They find out eventually whether the parent likes it or not.
