Sing

Sing's full name is Mak Chun Sing (麥駿昇), and he was born on January 11, 2002, in Hong Kong. He is one of two Hong Kong members of XODIAC, alongside Leo, contributing to the multinational identity that has been part of the group since debut.

• Sing moved from Hong Kong to South Korea in 2019 to begin his trainee life, meaning he spent several years living away from home while working toward an idol career before XODIAC finally debuted in 2023.
  
  

• Before becoming known as Sing, he was introduced during the OCJ Newbies pre-debut project under the temporary name "SM." By the time he was formally introduced as part of XODIAC, however, he had adopted the stage name fans know today.
  
  

• Sing has wanted to become a K-pop idol since he was young, so moving to another country and adapting to life in Korea was part of a goal he had been working toward long before XODIAC existed.
  
  

• He has named BTS's Jungkook as one of his role models, an especially fitting choice for Sing given his own focus on vocals and performance as part of XODIAC.
  
  

• Sing has one extremely specific hidden talent that is difficult for the other members to compete with: his right cheek has such a deep dimple that he can fit an AirPod inside it. He proudly demonstrated the unusual skill when XODIAC were asked to reveal their hidden talents.
  
  

• That dimple isn't something Sing considers ordinary either. When revealing the AirPod trick, he joked that he had never seen anyone else who could do the same thing, making it one of the more genuinely unique talents among the XODIAC members.
  
  

• When asked to choose an emoji representing XODIAC, Sing picked 🔥 because he believes all of the members have a fiery passion to achieve their goals. He said their ambition is to become the "hottest" group, turning a simple emoji question into a description of how he sees the team's drive.
  
  

• Sing wants XODIAC to become a group that fans feel proud to tell other people they support. Rather than focusing only on awards or numbers, he has described making fans proud of the group as one of his hopes for XODIAC's future.
  
  

• Sing is apparently one of the members who takes the longest to get ready in the morning, so sharing a schedule with him may require considerably more patience than sharing one with some of XODIAC's faster-moving members.
  
  

• Although Sing has spent years speaking Korean while living and working in South Korea, Cantonese remains especially meaningful to him as the language he grew up speaking in Hong Kong. His multilingual background has allowed him to connect with fans in different markets as XODIAC's international activities have expanded.
  
  

• Spending so much time in Korea has created a funny language problem for him: during a 2026 Hong Kong interview, Sing admitted that after living abroad for so long, his Cantonese can occasionally become a little "stuck", even though it is his native language.
  
  

• X-UNIT's "Still Here" holds special meaning for Sing because it is performed in Chinese, the language he grew up with. He said that connection made the song particularly close to his heart compared with the other tracks on the unit's debut mini album.
  
  

• Sing had actually never watched the famous K-drama Boys Over Flowers before X-UNIT was told they would remake "Because I'm Stupid," originally performed by SS501 for the drama's soundtrack. He initially thought the idea was a joke before watching the series and realizing the group could make the ballad work.
  
  

• X-UNIT's To.U gave Sing an opportunity to show more of his vocals through ballads and slower pop songs, styles that the four members felt they hadn't been able to explore as extensively through XODIAC's full-group music.
  
  

• Sing is interested in appearing on variety shows because he believes the format would allow fans to see a more relaxed and natural version of his personality than they normally see through choreographed performances.
  
  

• Returning to Hong Kong as a member of XODIAC has been particularly meaningful for Sing because it allows him to come home not as an aspiring trainee but as a professional artist. In 2026, he and Leo spoke about the excitement of returning to Hong Kong and meeting local fans after building their careers in Korea.
  
  

• When XODIAC held a Hong Kong fan meeting in March 2026, Sing and Leo deliberately stayed in Hong Kong for a few extra days so they could enjoy being home. Sing described the experience as making him feel both happy and fortunate.
  
  

• His connection with Leo extends beyond simply being XODIAC's two Hong Kong members. During their 2026 trip home, Sing talked about making plans with Leo to go out for chicken hot pot, giving the pair a chance to enjoy familiar Hong Kong food together away from their schedules.
  
  

• Sing's experiences as a Hong Kong artist working in K-pop have made him part of a relatively small group of idols who have built careers across both the Hong Kong and South Korean entertainment environments, something that also helps XODIAC communicate with a broader international audience.
