Nana Ou-yang and Roy didn't get married. They just wanted to be parents in the TV series "Boys in Beiling", but they didn't get married in reality.

However, in reality, Nana Ou-yang and Roy have a certain friendship. In the love song Rainbow Clouds written by Roy himself, the lyrics "I have a lot to say to you" are repeated many times, which can correspond to the last sentence "Just wait for you, tell me" in the song "Warm Your Winter" published before Nana Ou-yang.
