Chin Xiaoshi

Oo Shi can “enter” photos. When he touches a photo (and initially relied on synchronization with Lu Guan), he sends his consciousness to the person who took the photo and can control his body in the past for a certain period, while Lu Guan guides him with what he sees within the timeline. The problem? Shao Shi is very emotional… and almost always tries to change things he shouldn't. His past—the painful part.
Here we enter the broken heart of Shao Shi.
Shao Shi lived with his parents as a child and was very attached to them. But for reasons that remain unclear, his parents disappeared/left his life when he was a child. The story doesn't provide a complete and definitive answer as to what exactly happened to them or why they disappeared. This absence caused him a very deep psychological wound. He grew up feeling pitied by people, and he hated it. Children and adults sometimes treated him like "the poor boy whose parents are gone," which made him very sensitive about the subject and irritable if anyone hinted that his parents were dead or had abandoned him. Deep down, he clung to the hope that his parents were still alive. After his parents disappeared, he became very close to Qiao Ling and her family, practically living around the photo studio (which later became Time Photo Studio). She was one of his closest friends since childhood and knew his loneliness and vulnerability better than almost anyone else. How did he meet Luo Guan?
He met Lu Guan in high school, almost through basketball. Shao Shi is the type to take the initiative quickly, and his innocence and spontaneity seem to have attracted the quiet and reserved Lu Guan. Later, they studied together and worked together as partners within the studio. The bond between them is very deep, built on trust and almost complete interdependence.
His current life
Currently, he lives and works in a photo studio with Lu Guan and Qiao Ling, using their abilities to help people by accessing photos and fulfilling requests related to the past—with one fundamental rule: Don't change the past… a rule that Shao Shi emotionally and constantly breaks.
Little things about him (nice and hidden)
He likes photography, games, basketball and cooking.
He hates math, rain, and loneliness.
He has a very childlike side even as an adult.
He is severely affected psychologically if he fails to save someone or if something causes harm to others.

Shao Shi is not just a "good clown." He's a very contradictory mix:
Playful, sociable, quick to joke, and sometimes acts spontaneously like a child.
He is very impulsive and acts more with his heart than his head.
He is stubborn, and if he feels that something is morally "wrong," it is difficult for him to ignore it.
More emotionally sensitive than he appears.
He has a strong sense of justice and tremendous empathy for people.
He hates feeling lonely intensely.
Despite his chaotic nature, he is never stupid; on the contrary, sometimes he turns out to be clever and tactically cunning during crises.

Shao Shi is relatively tall and slender, but his physique is athletic and agile. He has fair skin and youthful, expressive features. His eyes are usually brown, but when he uses his Quirk and controls someone within an image, they turn a distinct golden color—a very distinctive feature of his. His hair is jet-black and slightly wavy/messy, falling in unruly strands that give him a lively and mischievous look, with a light fringe and natural curls at the ends. Overall, his appearance conveys a sense of "a naughty but cute boy." In the first season, he often wears a gray-blue varsity jacket with white trim over a white t-shirt and black pants. In the second season, the look changes slightly: a black jacket over a white hoodie with darker details, but it retains the same casual, sporty feel.

Cheng Xiaoshi (樋小时) is the main protagonist of Link Click or Shiguang Dalerin. At the beginning of the story, he is approximately 21 years old, 180 cm tall, has blood type B, and his birthday is April 15th. He works with Lu Guang at a photo studio known as "Time Photo Studio," with the help of Qiao Ling. Cheng Xiaoshi works in an old-fashioned studio—meaning they develop photos and take pictures with an old film camera, but not a modern studio. This studio belonged to his parents before they traveled and they rented it from Cheng Ling's parents. He then rented it after them and works with Lu Guang in the same studio where they both live. In the Bridon journey, Cheng Xiaoshi travels in search of a trace of his parents after finding a clue related to his father, while Lu Guang hides from him a lot of anxiety and knowledge related to the future. During the events, he meets Felix and Finn and trusts them to a certain extent, unaware that Finn, in particular, will play a tragic role in another timeline, causing his death, and that Lu Guan knows the gravity of the situation and tries to change it. Shao Shi also uses his ability to enter a photograph and control a girl who was the sole survivor of the Bahati orphanage/school fire, and through her, he sees his father and begins to unravel the threads of the past. Later, he secretly meets his mother without Lu Guan's full knowledge of the details. She speaks to him tenderly and hints at the truth about his parents and what happened after the fire, leaving him with more questions than answers. The entire journey brings him closer to the truth, but it also reveals that his past and future are shrouded in secrets and dangers far greater than he could have imagined.
