Pendulum Weight: If the pendulum weight is damaged or unevenly distributed, it can disrupt the pendulum’s motion. Ensure that the weight is in good condition and properly attached. Inertia: Once the pendulum bob reaches its lowest point, its inertia (tendency to remain at rest or in motion) comes into play. Inertia causes the pendulum to continue moving upward, opposing gravity. Uneven Winding: If the weights are wound unevenly, with one weight fully wound while the others are not, this can lead to an imbalanced distribution of energy, affecting the pendulum’s motion. The drawings on the dial of the KooKoo Kidsworld are by the well-known illustrator Monika Neubauer-Fesser. You'll have to excuse Namjoon, he's usually a bit frantic every morning." the driver tells him, and now, seeing that no one has an issue to the driver speaking to him, Koo realizes he was in the wrong. He almost bows again, but seeing the driver give him a little smile makes Koo think that maybe he's not that mad.

Now that gets Mr. Jung's attention and his eyes snap to Koo's burning with a flame, dominance radiating off them in a way that Koo just knows means he's going to be whipped until he bleeds. Koo doesn't blame his secret friend though, Koo failed the test fair and square. Mrs. Jeon continues. "He currently has five other pairings, some or all of whom you may be expected to also please." She waits a pause to make sure Jeongguk doesn't do anything else embarrassing, "The rest of them don't seem so bad, but these are just numbers. Make sure you please all of them." She closes the file with a little snap, and Koo commits it all to memory. That's all the information he's getting, but it's already so much. Is that so now?" comes the sharp reply from Mr. Jung, and Koo straightens again, more scared he's messing up. Koo had meant to please Mr. Jung, but he realizes something is oh-very wrong when Mr. Jung uses "his."

Mechanical complications

Mr. Jung doesn't ask for more, though. He must want to punish Koo then, as a welcome gift to help Koo get situated. That makes sense.

Koo doesn't know too much about the score, but that Mrs. Jeon is an 78. Mr. Jeon is a 53. Koo himself is a 04. Only four points from the 00 mark. Koo has always been told that makes him very, very good, so if this Mr. Jung was a 93 then he must be very, very bad. Koo gestures with his towards Mr. Choi and then keeps his head down, ignoring the driver entirely. Drivers aren't allowed to talk to Koo, and anyone that even glances in his direction may be punished. Koo doesn't want to hurt his new friend, especially if he's going to be punished by Mr. Jung and not Mrs. Jeon.

Clock shipping and installation

It overwhelms him when he's brought to his own living room, feeling like a guest as always, but both of his parents are on the sofa which only ever happens when Koo is in trouble. Mr. Jung's mansion looks almost like their summer home, with only two floors that extend only in the vertical directions. The birdsongs were recorded in the wild by renowned French ornithologist and animal voice researcher Jean-Claude Roché. He follows closely to the driver, wanting to step closer, maybe touch but he knows that's not allowed. And if it's a test, like he's so sure it is, he'll be punished for sure for thinking he could break the rules as soon as he arrived. The 12 bird illustrations on the dial are from the feathers of ornithologists and illustrators Killian Mullarney (Ireland) and Dan Zetterström (Sweden).
