ShiGuang

"Well done, new boy. We'll be partners in the future."

- Cheng Xiaoshi, about Lu Guang in basketball.

ShiGuang is the slash ship between Cheng Xiaoshi and Lu Guang from the Link Click fandom.

Canon
Cheng Xiaoshi and Lu Guang are both the main characters of Link Click, with each of their own respective powers. Lu Guang can see anything that has happened in a photo within 12 hours of it being taken, and Cheng Xiaoshi can enter the body of the person who took the photo. By clapping their hands together, Cheng Xiaoshi enters the time of any specific photo that Lu Guang is holding.

The first episode begins with Lu Guang reminding Cheng Xiaoshi of the rules of going back into time. He gets to the third one before the dark-haired man cuts him off saying that he has already repeated it a thousand times. Cheng Xiaoshi extends his hand, and after a moment of hesitation, Lu Guang fives it.

Qiao Ling later comes into the shop with a new order for the Studio, while Cheng Xiaoshi is playing on his phone and Lu Guang is wiping down cutlery. Lu Guang asks Qiao for the pictures, and she happily complies with the pet name "Guang Guang". Cheng Xiaoshi snickers, making fun of her before getting reprimanded again. The girl sighs, and says that she "Wouldn't even give him a glance if it wasn't for [Lu Guang]." The mission is explained and Lu Guang recieves an image taken by Emma, their chosen 'body'. Cheng Xiaoshi leans over Lu Guang's shoulder to comment on the image, calling it "Midnight poison!"; Lu Guang activates his ability on the photo. When he finished, he looks up and tells Cheng Xiaoshi that they have a chance, but only one. At this, the man grimaces.

Cheng Xiaoshi is quickly transported into Emma's body and Lu Guang warns him not to be a drama queen before he can do anything unbecoming. Lu Guang also stops him from eating the spring rolls and directs him to answer to Emma's boss politely. Cheng Xiaoshi answers in a fake-cheerful tone instead, and then sarcastically asks Lu Guang if he was satisfied yet. The man just sighs and puts his head in his hands. With Lu Guang's instruction, Cheng Xiaoshi plays his part well and is safe from suspicion. Emma is directed to prepare material for a team meeting the next day, and when asked, Lu Guang reassures him that he's there and will guide him.

Fanon
Despite their contrasting personalities, Xiaoshi and Guang typically get along well. They occasionally fight over small things, but it is mostly playful joking. Their characters and aesthetics draw similarities to NorRay, another duo with black-and-white-hair; one person with a serious personality and another with a more carefree personality. ShiGuang is the most popular ship in the Link Click fandom, and the ship has a decently big fanbase too. On AO3, it's the most written ship under the Link Click tag. Despite there being rival ships, none of them are as popular as ShiGuang.
