Having learned important values when it comes to man-woman relationships through the previous ones of their parents, they promise each other not to be too close, not to be too opposing, and to merely keep a vague and comfortable distance.
On one hand, Saki, who has worked in solitude for the sake of her family, doesn't know how to properly rely on others, whereas Yuta is unsure of how to really treat her. Standing on fairly equal ground, these two slowly learn the comfortable sensation of living together.

4. I Raised A Black Dragon
The witch, Eleanor Asil, has fifteen previous convictions.
And the transmigrator, Noah Park, had no intentions of being involved in the novel’s original plot of the dragon beheading the villainess. With that thought in mind, she abandoned her titles as The Wicked Witch and sought to live a long and peaceful life.
So she heads down to the countryside wrought with deep remorse for all her misdeeds. And all should be happy… or she thought.
“Please raise me!”
And so it would seem that she stumbled upon the heroine’s pet dragon — the black-haired kid that would turn ballistic and obsessive later on — imprinted the villainess as his mother. And to make matters worse, the male lead suspects her as the prime culprit of stealing the dragon.
“How long should I keep up with you?”
She thought he’d arrest her right away, but seems like the male lead was slowly becoming the dragon’s butler.
“Can I hug you?”
“No.”
“Then… can you hold me?”
The villainess believes that the dragon needs a bit of taming.
‘Oh, male lead, won’t you sign a life contract as a real butler?’
