What's the relationship between Roy and Nana Ou-yang?

I think Nana Ou-yang and Roy are friends. Both of them are outgoing, lively and cheerful, and like to make friends. Roy called Nana Ou-yang "Teacher Ouyang", however, Nana Ou-yang also called Wang Yuan "Two Brothers". It can be seen from the address of these two people to each other that the relationship between these two people is actually very good.

Because if two people don't know each other very well, generally speaking, they won't call others by their flower names. So, it can be seen here that they are very close friends.

At the same time, they are partners. The two of them performed a play called Dominator, playing the leading roles of male and female respectively. I have to say that these two people are very talented in performance, because their two majors are actually in music.

But this does not affect their play in the play. It seems that their major is acting, and they are well-trained personnel. In addition to good friends in daily life and working partners, they are also alumni of the same school.

Nana Ou-yang and Roy study at Berkeley College, and Nana Ou-yang is Roy's senior. Presumably, after Roy arrives at school, Nana Ou-yang will do his best to help Roy adapt to the school environment as soon as possible.

As we all know, when you arrive in a foreign land or country, you will feel a great sense of insecurity and miss your hometown very much. At this time, if you have a familiar person around you, it will make you feel less difficult, and these two people can take care of each other in a foreign country.
