The Daily Life of the Inventor in Another World

Next Morning

When Marcus opened his eyes, the first thing he saw was the ceiling of his room. Everything seemed normal, just as he liked it...

Or at least, it should have been. But instead, he felt a heat source next to him. Rather than reacting immediately, he took a deep breath and inhaled the familiar scent of his devilish companion.

He realized that Serafall had decided to sleep with him. Instead of reacting awkwardly, he simply wrapped his arm around her and chose to continue sleeping, since he still had about an hour before he needed to wake up.

Hmm, sleeping with Sera is quite nice. I think I could get used to this every day, he thought as he drifted back to sleep.

Serafall, who had been sleeping on his side, smiled contentedly. She had been curious about his reaction to her presence, and to her satisfaction, it was a very positive one.

Since he seemed to enjoy cuddling, she decided to wrap her arms around him as well. The black-haired devil lady stayed like this for a few more minutes before she would need to move.

At 7 o'clock in the morning, an alarm clock rang in a certain room. Marcus opened his eyes and quickly got out of bed. The first thing he did was rush to the shower to shake off his grogginess.

After the shower woke him up properly, he dressed in his school uniform. It was then that he realized the heat source beside him was gone. He turned around and scanned his room.

His room was as simple as possible, just the way he liked it, preferring to focus on customizing his workshop rather than his living space.

After a quick search, he realized that Serafall was no longer in his bed. She must have left before he had even woken up.

I didn't even feel anything when she moved. Is she really that sneaky, or am I just a deep sleeper? he mused. Since she was registered as his familiar, his barriers hadn't detected her departure.

Once he was fully dressed, he made the bed and went downstairs to the kitchen.

When Marcus entered the kitchen, his brain briefly stopped processing.

He saw Serafall animatedly talking to his mother and father. She had her hair styled into a high ponytail and was wearing smart glasses. She was also dressed in his school uniform, making her look no older than a smart sixteen-year-old girl!

That was the thing about the current Leviathan: she could easily pass for a young adult or late teen.

"Mark! You never told us you were 'friends' with an older girl!" Marcus's dad grinned, purposefully emphasizing the word "friends."

Marcus rolled his eyes. He had been trying to spend less time with his family on purpose, wanting to appear indifferent to them to anyone else—mainly the devils. The less attachment his enemies thought he had, the more leverage he held.

But it seemed that as soon as he gave Serafall a little space, she took it to the next level.

Fortunately, he knew that she had a large amount of affection for him. His Ars Goetia confirmed that she was simply curious and wanted to learn about his parents, not use them. That was the only reason he allowed her to act like a "16-year-old cute girl" who was interested in the loner Marcus.

"Yes, we've been friends for quite some time now. She only decided to come here because it was convenient," Marcus said with a sigh, taking his seat. Amusingly, it was right next to Serafall. Seeing the coincidence, both of his parents grinned like fools.

"Indeed, I've known him for over a year now, and yet, I still discover new things about him every day," Serafall said with a smart-sounding tone. Her acting was so spot-on that even Marcus felt a chill run down his spine. It was no wonder she handled diplomatic relations so well...

"I see... Honestly, Son, I thought you were going to marry your BMW at this rate," his father said sagely, as if expecting Marcus to marry his car.

Marcus rolled his eyes as he started drinking his tea.

His mother chuckled in amusement while Serafall simply smiled.

"Don't worry. I'll make sure he doesn't do that," Serafall assured them in a playful tone.

"We leave him in your hands then, Sera," his dad said with a serious nod.

Marcus groaned inwardly. Why did they take these small, inconsequential things so seriously?

"Is there any particular reason you decided to insert yourself into my morning routine?" Marcus asked, rolling his eyes.

Still, he couldn't help but enjoy how she was hugging his arm and acting like a doting girlfriend.

"And why not? I've already altered some of the hypnosis Venelana did. They're much happier now, knowing their son has a girlfriend!" Serafall said, continuing to hug his arm.

As they reached the school, Marcus could already feel some people staring at the black-haired devil girl.

Her beauty was supernatural, and to be perfectly honest, he had started to completely dismiss the "regular" girls around him. They seemed... colorless, lacking the vibrancy that Serafall had. While he could still be attracted to them physically, actually being interested in them? Not anymore.

"As long as I have my time and they're not snooping around behind the garage, I suppose it's fine," he said with a sigh. He could accept the fact that Serafall was advertising herself as his girlfriend.

"Don't worry, I dealt with that the moment I started the hypnosis. They think the area behind the garage is just for miscellaneous stuff. They won't check it unless a cleaning is done," she explained.

"I see. I suppose I can make it look like that," Marcus said with a nod, considering how he might deal with it.

"Indeed. Now, why don't we act like an actual couple for once?" she suggested, purring seductively.

"As long as you don't overstep your boundaries, Sera, I'll entertain this idea," Marcus replied with a nod.

She smiled at that.

"Don't worry~~~ you forget that I'm a devil~~~ I can adapt to any situation. I know my boundaries. I won't interfere or demand too much attention. But I will be there when you're free... or more precisely, you should call me when you have the time... I can always help you~~~ in some way~~~" she winked seductively before entering the school.

Marcus assumed she had already inserted herself into the educational system of his country.

Hopefully, Heaven or the Norse wouldn't notice her profile picture… Well, he didn't think they even had profile pictures yet.
