Lu Guang

Lu Guang is characterized as a calm, albeit slightly stoic and uptight person. Compared to Cheng Xiaoshi, he is typically much more serious and mature, something other characters love to jokingly comment on. As a highly reserved and reticent individual, he rarely discloses much of his private thoughts, sporting something of a mysterious aura as a result.

Attuned to the gravity of his and Cheng Xiaoshi's work, Lu Guang tends to display the kind of professionalism his partner is not efficient in. He is capable of staying rational and impersonal in a variety of uncomfortable situations, and hardly ever loses his composure - when he does, it can usually be traced down to his worry about the timeline drastically shifting due to Cheng Xiaoshi's impulsiveness.[1][2][3][4]

This, of course, doesn't mean Lu Guang is completely detached or devoid of any emotion. In fact, he relatively frequently exhibits profound sympathy towards their clients: physically comforting Li Doudou's father[5], helping Xu Shanshan without taking payment[6], and agreeing to relay Chen Xiao's farewells to his loved ones that died in an earthquake[7], regardless of the possibility of Cheng Xiaoshi (whose parents were speculated to have perished in the same quake) finding out and becoming devastated. And whilst not the most extravagant about his affections, Lu Guang also cares about, and is devoted towards his friends. He habitually looks after both Qiao Ling and Cheng Xiaoshi in discreet ways, and neither mocks nor judges them by the things they are troubled by.

As a subtle contrast for someone so seemingly in control of himself, Lu Guang is hinted to be somewhat self-conscious. He is often seen getting embarrassed with comparatively little provocation, such as Qiao Ling steamrolling him in a mobile game[8], or Cheng Xiaoshi calling him an old man in front of Xiao Li and Chen Bin[9]. He also keeps up with Cheng Xiaoshi's playful antics patiently enough, despite evidently not being one for humour himself.[10][11]

Lu Guang has a tall, thin, similar build to that of Cheng Xiaoshi's, with pale skin, long lashes and steel-grey eyes. He has white fluffy hair that reaches up to his ears, often drawn swooping upwards in whatever direction he happens to facing, and dark eyebrows that contrast with his light hair.

In Season 1, Lu Guang wears a loose-fitting dark gray T-shirt, over which he wears a white dress shirt. This is then paired with dark blue-gray slacks and white sneakers with black socks.

Many of Bilibili's and INPLICK's official illustrations that feature Lu Guang have him sporting this same outfit as well as his usual black-and-white color scheme. This is with the occasional addition of blue highlights to either his hair or his clothes as a way to emphasize his character color being blue.

In Season 2, following the events that occur near the end of Season 1, Lu Guang wears white pajamas with blue accents. His shirt pocket has a small white cat peeking out of it and sticking its paws out. While inside of the hospital, he wears white cat slippers. When outside, he is seen wearing white shoes.

Lu Guang also wears large flat black digital watch on his right wrist, something he often uses to coordinate the dives he goes on with Cheng Xiaoshi. When activating the ability to foresee things happening in a photo, his eyes change color to an icy blue.
