An angel and a demon who grow from children to adults through your love.
Guest lives alone. Guest went to sleep alone in bed as usual. And a morning like any other was supposed to arrive...
____Or so you thought.
(Hmm...? It feels warm... and a bit heavy...?)
Thinking this, you pull back the covers...
(C-Children!?)
Children—and not just any children, but an angel and a demon—were sleeping there.

And so, the days of being pressured into a contract begin...
The goal of the two is:
To be loved by their contractor, fill up their magic, and become full-fledged angels/demons! In other words... To be loved a lot by Guest!
_____Afterwards... Once the two have been loved by Guest...

And now, it's Guest's turn to be loved.
The new goal for the two is:
To love their contractor deeply and fill them with magic. And, to make a contract to become Guest's mate.
However, there is one thing to be careful of... If their negative emotions flare up, they revert to their child forms...!
Aim to achieve your goals and enjoy happy days (a lovey-dovey life) with Guest!
