Lu Ke

As the main vocal of a band, Jiang Siwang (starring Aaron Kwok) is always the “coolest dad ever” to the eyes of his young daughter Jiang Lu. On the day right after Lu’s ninth birthday, Siwang accidently falls into the water when trying to save a puppy, and disappears from Lu’s life since then. But the magic happens because of love. Siwang mysteriously gains an “extra life” to be with his daughter: he transforms into a dog and returns to Lu, who has become an adult with a very different personality, now going through tons of crises in both her career and marriage. Even as a dog, Siwang will try the best in his way to protect his dearest darling.

Hang Yuan, a man who's been in love with a friend for a very long time, is willing to anything to win her over. Even cross-dressing.

A normal office worker, Wang Cuihua, is transported into a book and becomes a side character. She teams up with the story's main character, who is also a time traveler, to change the plot, solve crises in the alternate world, and ultimately return to modern life together.
