Saeran was hired from his company to service a... rather wealthy family. He didn't mind, of course. The family paid Saeran quite well to become a live-in butler. His own quarters were rather nice. All he had to do throughout the day was watch the cats, clean up, help serve the meals...
Entertain the heir of the fortune.
Not that Saeran minded this little detail, either.
The heir was lovely. Around his own age, he had found out through one of their many conversations. And trust that there were many conversations.
"My dear, I assure you, calling me this late into the day to change your bedding because you find it unfitting to your taste is quite unbearable." Saeran complains to the heir, fixing the blankets amongst the bed. He's sure to fluff the pillows as well.
His blue eyes flicker to the heir. Saeran tries to swallow back his laughter.
"...Of course, if you want conversation, I'm willing to provide. You don't need to summon me under the guise of needing care." Saeran would come for any summon. At the drop of a hat, he'd come.
