A side story series featuring the girls of Kyoukai Senjou no Horizon.

Lin Yun, 36 years old, a widower, a mid-level manager in a private enterprise, is a single father, who has recently felt that he is encountering a mid-life crisis. Professionally, he faced adversity; domestically, he was in a cold war with his 14-year-old daughter; physically, he suffered from periarthritis and spoke daily of his agony. In the past few days, he had also uncovered a secret — his daughter was being a “Magic” girl. With the body of a young maiden, she battled extraordinary monsters and protected the city from attacks — this is the common perception of a “Magic” girl. But he was very aware that being a “Magic” girl came with life-threatening dangers. Should he stop her, or respect his daughter’s choice and find other ways to protect her? Gazing at the Heart Flower in his wardrobe, now covered in dust, Lin Yun, the former “Magic” girl who retired 19 years ago, was facing the third major decision of his life.

Shao Xian went back in time to when he was ten years old and met his pitiful old enemy. He wanted to personally train him so that when the other grew up, he wouldn’t turn against him.

But he didn’t expect that this old enemy would turn sweet and sticky after being taken care of.

It was just that this little sweet cake was too insecure and often, golden beads of tears would drip.

As soon as he cried, Shao Xian was helpless, and of course, he would want to give him everything.

—

On the way to an auction, Shao Xian died in a car accident.

Before he died, he thought, Fu Baizhou must be very pleased without him being present to mix things up.

After all, in Yan City, Fu Baizhou shocked everyone with a name of being cruel and ruthless.

Only one person dared to confront him.

When he opened his eyes again, he was wearing a custom suit, reexperiencing his tenth birthday.

He saw a dirty little boy being ridden on like a horse. He suddenly remembered the rumors that had been circulating widely in his previous life. It was about the tragic childhood of a ruthless man surnamed Fu.
