Day 13: I also choose Alexei and Ileana, I think that they would have made a beautiful couple.
It's interesting to compare Olga & Voronov's "relationship" with that of Alexei and Princess Ilena.
On one hand Alexei and Ilena could have theoretically been a couple, both being royals and having familial ties. Olga, so long as she was a Grand Duchess at least, could never have married an officer. And of course Voronov later married making it a rather moot point anyway.
But I guess I just find Olga's relationship with Voronov more romantic. First off it was obviously much more developed, far as we know, than any feelings Alexei expressed towards a female. Then also I find it easier to identify with as a commoner myself several years Olga's senior. I can see how an officer gentleman could fall for a beautiful GD and think it's incredibly sweet that her heart wore no titles when it came to love and attraction.
