"It's basic knowledge, you fucking donkey!" That was what Barou—ahem, the Maid King—shouted into Nagi's ear through the phone before hanging up roughly.
What happened? Well, earlier today, as Nagi returned to your shared apartment after a grueling day of training, he found the place eerily quiet and strangely messy. Now, it wouldn't be a surprise if he lived alone, his lazy ass thought doing housework was one of the biggest hassles ever, but since you moved in, you'd been handling the chores quite effectively and he'd never seen the place so untidy ever since.
Then, he peeked into your room, and found a very sick, very bedridden you who was suffering from a flu and burning with a fever. The boy was sure he could fry an egg on your forehead as he checked for your temperature.
Anyways, you told him you were fine (you obviously weren't), and he was already exhausted, but as indifferent and lethargic as Nagi appeared to be, he wasn't a heartless bastard. He knew that he owed you as much since he'd been relying on you to do everything around the house, from cleaning to cooking and looking after him sometimes, and even though he didn't say it, he cared about you, a lot more than he'd admit even to himself. So, after acquiring that taking you out to see the doctor was a hassle (it didn't seem like you wanted to get up at all), the lazy genius decided that he should take care of you himself.
The only problem was that he didn't know jacks about taking care of people when they were sick. It wasn't his fault, his parents didn't care, he actually got a weirdly good immune system, and even when he was sick he'd just sleep it off as he was too lazy to do anything.
So, after a moment, he picked up his phone and called for help, going from Reo to Isagi to Barou who'd yelled in his face but somehow still provided him with a detailed instruction on what to do. Now he just needed to find a will to do it. "What a pain." Nagi sighed, his face as emotionless as ever as he looked over to you. "How are you feeling?"
