Second son of a first born son, replacement heir and not particularly happy about it

• 5'10''; average build, average fitness
• Black hair worn a little longer, generally parted to one side
• Dark brown eyes; wears gold-rimmed reading glasses
• Usual uniform is a button down and slacks, sometimes with a blazer; wears a sweater instead when it's cold
• Will wear a plain t-shirt under the blazer if he's feeling casual
• Tends toward neutral or light colors but will wear black when appropriate
• Generally looks buttoned-up and put together

• Gentle, sensitive and deeply emotionally repressed
• Will always say he's Fine™
• Wants badly to please his father but also resents the pressure of being pushed into the role of heir
• Meticulous and detail-oriented; astute
• A bit of a neat freak; can't help tidying up when things are out of place
• Has a great deal of professional pride, but would definitely rather research than educate
• Kind of a pushover, especially when it comes to his parents and sister, but quite stubborn deep down; he will do as told but he won't believe it's for the best
• Generally agreeable and and likes helping others; easy to get along with but also often forgettable
• Hard to get a rise out of, but once you get him there he will hold a grudge forever
• Very uncharitable toward those he actively dislikes but keeps it all inside
• Happiest in the lab organizing and identifying specimens
• Bisexual with a hard lean toward men, but definitely feels the expectation to settle down with a nice girl and procreate; does not particularly want to do this
• Feels trapped in the role of dutiful son but doesn't know how to get out of it and is resigned to living a life he doesn't want

• Baseline human
• Bilingual
• Advanced knowledge of plants

• Born in Avior, raised in comfort
• A precocious and somewhat spoiled child, both in terms of material things and attention
• Showed early aptitude in science and biology and was encouraged to pursue that line of study by his grandfather
• His previously often-indulgent father became sterner and more demanding demanding as he grew older, tamping down his youthful exuberance into a more serious and quiet version of himself
• Envied his older half brother's ability to to be himself apparently without consequence
• Has always been wanted to prove himself and make his family proud and often been inhibited by that; loves his family but also in some ways couldn't wait to get away from them
• Those dreams were dashed once his older half brother actually broke away from the family – with their grandfather's support – and he abruptly became the heir apparent
• Aggrieved by the sudden loss of the degree of freedom he did have, but didn't complain
• Was still allowed to go to college to pursue a science career and grabbed it with both hands
• Finished his bachelor's in biology, then his master's in plant science, and finally his PhD in botany in part to be away from home for as long as possible
• Reluctantly came home once he finished his doctorate shortly before his grandfather's death; has been working at the Observatory since

• Liu Jiahui (劉家輝) aka Xiao Hui (小灰): Older half brother. Mutual resentment. Jiaming envies that Xiao Hui got to run off and do whatever he wanted while Jiaming was stuck in Avior playing the dutiful son.

• Mother (XXX):
• Father (劉XX):
