Throughout his first two years at Hogwarts, Derek Alexander Jay never once questioned the wand that he bought. Derek, like most other wizarding students, believed that the wand was simply a tool for casting spells, and that he should be focusing his time and effort on studying and mastering his spells, rather than on his trusted companion.

It was not until his third year, while studying in the common room one stormy night, that Derek pondered if there was a better way to modify or alter ones wand in order to improve its performance. Why, if each one was different, should it not continue to be modified in order to better suit its owner? Why did witches and wizards willingly accept that their wand would remain the same over the years, rather than trying to enhance it and make it better?

This question consumed Derek's thoughts for what seemed like weeks. He became obsessed with the idea of wand-making and spent long hours poring over the Hogwarts library, searching for any scrap of information he could find on the construction, magic, materials, and art of wand-making.

The more he read, the more consumed he became, even going as far as to experiment on broken and old wands piling up in the school's hidden attic. Derek took detailed notes on the history of each wand and the techniques its original maker may have used, and he began to get a general idea of what could be done to improve upon it. It was around this point that Derek began to realize how knowledgeable he had become in the field of wand-making; how he could see small changes that could be made to the design and construction in order to improve durability, performance, magic, and even the bond between wand and witch or wizard.

Derek was quite proud of himself, albeit a little surprised, as the idea that began as a simple curiosity in his third year had now grown into a full-fledged passion in his fifth. Though he had yet to actually craft a wand of his own, Derek's talent, time, and dedication marked him as worthy of being a wand-maker in his own right

Derek, however, did not start down this path for the sake of fame or fortune, but rather for the sheer enjoyment and love of the craft. He believed that there was a perfection in every wand, and that it was up to him to help bring out that perfection in his wand-making peers.

Olivia grew up in a household where magic existed but it was not used directly infront of her most of her childhood. Maybe because her parents were afraid that Olivia might think its normal for parents to do magic and confess that in her muggle school. So whenever her parents used their wands it excited her. Then again for some one who dont understand what a wand is it just looks magical. But for someone who knows exactly what a wand is its more than just magical. Its everything.
Olivia is now in hogwards a place where she can study about wands as much as she want. Hence olivia tend to spend most of her free time in the library reading about intresting wands and wand interiors. Anything but charms homeworkd. The more she read about wands the more she liked her own wand. 26,7 cm holly wood and phoenix feather. The wand that chose her. And the more she liked her own wand the more she wanted to know about it. The more she learned about it the more explored other wands.
This thing is surely magical. She learned about every wand she could find. The more she read about wands the more she realised the art of making wands. It eventually became her habit that whenever someone new speaks with her she will look at their wands. And if the interaction is normal enough she will explain everything about it to the random stranger that she just met. Technically she was doing them a favour. They should know what they are handling and how powerful they are. Olivia thought about the interaction she had with Olivander's quite often when she read about wands. He is for sure the best wandmaker. Everything he had said about the wand choosing the witch and the wands interiors and the way he remembered every wand he had ever sold started to make sense to Olivia.
"I too want to be a wand maker. I want to learn about it. Its basically the equivalent to owning a dragon and specialising in dragons. Its so small and looks harmfull but they are the most powerful tool for a powerful wizard. The wand is not what makes the wizard. Its the bravery. But the wand surely helps. I will not stop reading about wands until there is not a single thing about wands that I dont know."
