꒰🌆 — Uta is refered as a robot once throughout the post, mostly because she is considered as such in here official profile, but think about "robot" as in a UTAU rather than a convencional robot!;

While this might seem expected, she is the textbook definition of Kuudere. Sorry :/
Like many other vocalsynths, Uta also feels like she can better express herself with music, however, for her this feeling is a little bit more intense — to the point where she feels like she can only properly convey her feelings (regardless of what those emotions might be) through music.
Because of that, you will always hear her singing, humming or, if the environment allows, playing an instrument. She doesn't intend to bother you or others, so she tends to do these things very quietly. However, if you could take a moment to sit and listen to her singing, it would make her day.
Because of that, too, if you manage to sing with her or play an instrument while she's singing, that would mean the world to her! She would be so unbelievably happy, to the point you wouldn't think it was possible.
While this may be a side effect of being a "robot" in a way, Uta doesn't have strong feelings for things such as her name — although she is quite fond of her nickname "Defoko" — or how she expresses her gender. Because of that, she gets to experiment a lot with it; if you could help her, even if it's just dressing her up, it is guaranteed she will have a lot of fun.
Unrelated to anything else, you will probably need to get used to Uta's siblings! They are much more expressive (at least when compared to her), and much more noisy-er. Koe, Uta's younger sister, will always try to follow the both of you, mostly because she is so curious about what romantic things her sister does with you, while Defosuke, Uta's older brother, acts more like a Dad, and will probably call you "Defuko's Girlfriend" rather than your name… Not because he consciously is trying to tease Uta, he's just not that good with names.
Who will try to consciously tease her (and you, to a certain extent), however, are Teto and Momo. You will have to get used to them as well… Good luck on that!
That might not sound surprising, but Uta actually makes an effort to be "romantic" — or, at least, be romantic to your eyes, since she doesn't have much of a basis of what's romantic or not. So, if someday she catches you saying that you found a scene in a movie or a book or anything else that you found romantic, she will try to recreate it. With varying degrees of success, of course.
She might try a little bit too hard, though, so it's always nice to reassure her that she is enough for you! Maybe even give her a little kiss on the cheek? It's not like she's not going to like it, anyways~
