Boris: Yuna found him kinda cold and off-putting at first, but once she got to know him better she grew to appreciate how concerned he is for his friends. Boris is sometimes concerned that the others might have a bad influence on Yuna, but she assures him she'll turn out fine.

Valeri: He's someone Yuna can go to if she's stressed about handling things in the human world and needs to talk about it, and he'll listen to what's on her mind and offer some advice or information, whatever he figures will help her. And Yuna is happy to comfort Valeri when he needs a shoulder to cry on.

Aleksandr: They get along very well. Yuna loves that Aleksandr takes such good care of the others, and sometimes she insists on pitching in when it looks like he's doing a lot at once. They both also love anything soft and pink!

Volodya: They support each other so much! Yuna does her best to cheer up Volodya when he's being hard on himself, reminding him how lovely of a person he is, and Volodya reassures Yuna that she's doing great (on her mission, and adjusting to the human world as well) and that she's been such a good friend to him and the others. They also love watching studio ghibli together.

Vladimir: Yuna loves hanging out with him, because they always find something fun to do together, and he also gives her the energy she needs when her day is off to a bad start. She loves how he hardly ever seems to run out of energy. Sometimes Vladimir lets Yuna in on his pranks as well.

Vasili: They're practically best friends! Vasili was the first one to reach out to Yuna when she first arrived, and from there they clicked. They always find things to talk about, and they love playing games and drawing together. They also understand each other, in the sense that they've both been overlooked because they tend to be outwardly open and carefree when they're also very determined to achieve what they set their minds to.

Viacheslav: Yuna was a bit scared of him for a while because of how brash and brutally honest he often was, but they grew to get along better the more they got used to each other. Now that they really care about each other, Viacheslav has become kinder to Yuna and more careful with what he says to/around her, and Yuna has become more comfortable chatting with him.

Sergei: He found it quite easy to connect with Yuna, and to this day they still love each other's company and make each other's day. They particularly enjoy going on walks (or ice skating in the winter) together. Sergei is often Yuna's buddy when the group goes out in a city or festival, and they get lots of their favorite desserts while they're at it.

Alexei: They clicked and bonded over their cheerfulness and resolve to brighten others' days, along with the fact that they're the two youngest in the group. They still get along very well and keep finding ways to cheer their friends or each other up.
