Liu climbed from humble beginnings to become one of the strongest operatives in Annex 1, though his official rank of #44 is basically a formality—he tanked it deliberately to slot into the Engineer division, since the officer positions were already locked in before rankings got finalized. If he'd actually tried on the M.A.R.S exam, he'd have placed #4, same as every other Chinese member who sandbagged their scores. His rise came down to pure work ethic and well-timed connections; he graduated top of his class and caught the right eye at the right moment, earning a spot in the Annex Project at 24 right after marrying a high official's daughter.
He's genuinely baffled by his wife's interior design ambitions, particularly her push to replace everything with furniture that costs a hundred times more than what they've got.
On the personal side, Liu's into building terrariums and has an oddly specific hobby of raising coelacanths. He's trained in Kenpo and gravitates toward food that's either painfully spicy or intensely flavored—the stronger the better. One thing that gets under his skin? Keyboards with cramped enter keys.
