I Raised Four Kids and Got Caught in a God-Tier Love Triangle

[Abandoned, don't read.] On the Continent of Divine Miracles, there lives a legendary ageless witch. Since witches have such long lifespans, they tend to develop some unusual hobbies. Helena's hobby is picking up kids and raising them. ~~ Many years ago, Helena picked up her first kid. It was an elf so beautiful he was beyond compare. Helena hadn't raised him for long before the little elf ran away. The second kid she picked up was a weak, innocent incubus. Under Helena's careful guidance, he grew up to become the brutal Demon King of the Demon Realm. Helena: “...Well, then.” Not long after, Helena picked up a shy, bashful human. Under Helena's care, he grew up to be a famously icy priest in the Church of Light. Helena: “...Sigh.” Later, Helena raised yet another kid who seemed perfectly ordinary. When he grew up, he became the human race's fated king. Helena made a special trip to attend the king's coronation, only for him to plunge a knife into her chest. Helena: “...Damn.” Only then did she realize that there might be something wrong with the way she raised them?! ~~ There is a saying on the Continent of Divine Miracles. There is an ageless witch: the Elf King's treasure, the Demon King's Achilles' heel, the Light Priest's ideal, and the Human King's obsession. “When the black moon rises over the Sea of Death, she will at last return with the tide.” 1. A tangled romantic rivalry, with many one-sided crushes. 2. Staying firmly committed to a one-on-one romance. Theme: Children's mental health must not be overlooked.
