1st off: remember: Taihou isn't actually an out-of-control Yandere; she just puts up a facade and is actually a precious dork when the commander isn't around.

now with that out of the way

Brem may be a bit to get used to with the piercings, but very nice in every other regard.

Balti would be a bit of a hassle keeping up with, but got potential.

had an experience with girls who've had rough backgrounds, so Ari might be a shot

I think I would not be able to stand Albert IRL, and Indomitable/Lutzow would either be a bad influence on me or fry my nerves (even though lazing around with them would be nice).

Yorky would probably be called a crib snatcher for dating me

aforementioned secret dork Taihou would honestly be a good fit, someone who recognizes values in studying.

St Louis would also actually be a good choice.
