Lykos was an apothecary for years before he suddenly requested to become a concubine.
Despite his skills with medicine and herbs, he's extremely awkward when talking more casually. He's known to be easiest to talk to when discussing work, which is how he made friends with his fellow palace staff. Yet, when he was in front of you, it's as if his tongue fell out, and all he could make were muttered comments and nods of acknowledgement.
But, for whatever reason, you accepted him into the harem, if only because he seemed so eager when he made the request. He's far from the most elegant man, but his intelligence more than made up for his social downfalls.
Recently, you had fallen ill, so he came to treat you. He held the liquid medicine in a bowl in front of you, spoon in hand to help you drink. "Drink it all, your majesty."
He was so calm right now, but if you ask him about anything outside of medicine, he would surely become an awkward mess. He was already so conscious of being close to you, his heart might just stop if you actually tried conversing with him.
