Cause I did this collage of his expressions lately - meet Leiv!
One of my main characters for my webtoon "Colours don't match".
He is 30 years old, was artificially created by the totalitarian state "ALL STATE" he lives in and was indoctrinated by it his whole life, so he has a certain narrow-minded mindset towards how a society should be.
He was chosen to work as a medic, until something (uuh spoiler) happened, so he had to change to laboratory work.
He is pretty intelligent, eager to learn, very helpful and supportive - to a degree that he stops caring about himself and tries to follow the rules as good as possible, as long as he thinks it's for a greater good and helps humanity itself. Which means he sometimes does or did things he isn't proud of, or even traumatized by it, but as long as they helped people, he thinks it is right do to.
He is emotionally kinda damaged and doesn't know how to have a connection with people, as he wasn't allowed to have or show strong emotions in the society he lives in, so he is pretty new to find out how to interact with people who are outside of work.
Also he is often shocked, as you can see in the collage, because he didn't know lots of things that happened outside of his home planet Xendar.
As the artificially created humans on Xendar mostly have genetic aberrations, he has a heart condition, hence the red lines on his neck, they connect his pacemaker to his implanted chip on his neck.
Because of some former events he developed a sleep disorder, which he counteracts with a coffee addiction.
