He was looking for a Korean singer's music video that told the story of a playboy and a bartender in a bar. The male lead gave the female lead a cola ring.

If the male caller was Lee Fugui's Korean singer, the female protagonist was called Jeong Suyeon, the novel's title could be either 'The Blooming of Riches' or 'Lee Fugui's World of Jeong Suyeon'. However, the exact name depended on the plot and setting of the novel. As a fan of web novels, I can only provide some basic information, but I can't give the exact name of the novel.

Okay, according to the information you provided, I found a novel called " The Mysterious Ruby Ring of Time Travel ". It tells the story of a modern girl who transmigrated to a fantasy world and obtained a ruby ring. She then met the male protagonist and what happened during their adventure. This novel is not bad. You can read it.

The name of the novel might be Nightlife.

There were a few novels that met this requirement. They were " The Hall of Rebirth Band,"" The Godfather of Rock and Roll,"" Star Musician," and " The Queen of Rebirth, Starting from the Top." The female protagonists in these novels loved music very much, and some of them were even the lead singers of the band. I have these novels in my recommendations. I hope you will like them.😋

I recommend "Hey, I'll Teach You How to Fall in Love" to you! The female protagonist's boyfriend was with her best friend, so she turned to the male protagonist's playboy friend, Lu Chengcheng. Later on, the two gradually got together. Sweet ~ I hope you like my recommendation. Muah ~😘

😋I recommend the following novels to you. I hope you will like them: "The Explosive Producer of Rebirth." The male protagonist, Yu Sheng 'an, had traveled to a parallel world similar to Earth and became a bar singer. After one of his Cantonese songs was uploaded online, his popularity skyrocketed. Later, he even released the Mandarin version of "Ten Years," becoming a popular singer. This book belonged to the category of urban entertainment star novels, which matched the plot of the male lead being a bar singer. I hope you like my recommendation. Muah ~

There were a few recommended Korean novels and idol dramas, in which the male lead was a singer. These novels included " The Two-Faced King Loves the Evil Concubine "," The Evil King's Sleeping Concubine "," The Young Master Is Too Enchanting ", and " My First Love Was Not Gentle ". However, no specific Korean dramas or novels were provided, so it was impossible to give a more detailed recommendation.

I recommend the modern romance novel "Paranoid CEO, Marry Me" to you. It tells the story of the love story between the female protagonist and the male protagonist of the paranoid CEO after she was kidnapped to an uninhabited island. The female lead was a spicy bartender, and the male lead was a rich and powerful CEO, Shuang Jie's favorite novel. I hope you like this fairy's recommendation. Muah ~😗
