Actress Yang Yu-jin appeared as the creator 'Bbangmeokda Saljjin Tteok' in episodes 1 and 2 of 'YouTuber Golden Bell,' an entertainment program on the YouTube channel 'Channel Fifteen Nights,' showcasing diverse charms and earning recognition for her variety show instincts and wit.

In the first episode, Yang Yu-jin revealed her friendship with Leo J and engaged in lighthearted conversation. When Leo J greeted her, she responded, "Oppa, it's so good to see you," and lifted the mood with clever reactions even to playful questions. She introduced herself, saying, "Unlike in my videos, I'm an introvert, but I'm a tteok who creates situational comedy by playing various characters," and revealed that she started her TikTok activities while majoring in acting and has been active as a creator for six years. In the following perfect pitch game, she succeeded on the first try, earning praise from Leo J: "As expected of an actress!"

Her performance continued in episode 2. In the 'Say It in a Row' game, Yang Yu-jin quickly guessed the correct answers and helped her team. In the detective game, she carefully observed the other cast members' behavior and participated in the deduction, showing an active attitude by suspecting that Hong Sound never let go of a drink and proposing a mission of holding tteokbokki in her mouth for 10 seconds. When the culprit's identity turned out different from her prediction, her surprised expression drew laughter.

The makeover video the two appeared in together recorded 19.89 million views as of the recording date. Producer Na Young-seok praised Yang Yu-jin's acting, saying she pulled off three different concepts as if they were different people, commenting, "All three look like different people." When Na asked about her connection with Leo J, Yang Yu-jin jokingly replied, "I'm the one who keeps my oppa fed and taken care of."

Meanwhile, Yang Yu-jin is pursuing both acting and creating activities, playing Ha Young-joo in the JTBC drama 'Apartment' and Chae-yeon, the manager of Oh Ha-na (played by Lee Yeol-eum), in the ENA drama 'A Dream for You.'
