Isn't the protagonist's main quest dating girls?

Living each day with the Student Council President, Wu Yan's life was truly fulfilling. Even though he was just helping the Student Council President with cooking and serving tea, having such a beautiful, two-dimensional girl around him every day made Wu Yan extremely happy. Although our Student Council President initially intended to give Wu Yan only the title of butler, since she didn't need one and hadn't thought about having one, if Wu Yan hadn't requested it himself, even the butler title might have been spared. The Student Council President merely wanted to help the 'homeless' Wu Yan.

However, in these past two or three days, Hinagiku had gradually become inseparable from Wu Yan, thanks to his service. The reason was that Hinagiku had been conquered by Wu Yan in these two or three days. Of course, only her stomach had been conquered...

With the 'Culinary Arts Proficiency' skill, Wu Yan's cooking skills were at a world-class master level. Whether it was making tea, cooking, or making pastries, Wu Yan was proficient in everything. In just two or three days, he had managed to conquer Hinagiku's stomach, who was fine with simple meals, and made her picky about food.

With the idea of capturing a person's heart by first capturing their stomach, Wu Yan changed the variety of dishes and desserts he made for Hinagiku every day. Not only did he successfully capture the Student Council President's stomach, but he also made Hinagiku a little bit fatter.

If the stomach is conquered, will the person be far behind?

Wu Yan fantasized about this every day...

And so, three days passed in the sometimes warm and sometimes playful interactions between Wu Yan and Hinagiku. On this day, Hinagiku brought Wu Yan good news.

Smiling, Hinagiku handed a document to Wu Yan and said, "Congratulations, Yan. Starting tomorrow, you'll be a student at Hakuhou Academy."

It's finally here!

"Ding! Task 1 completed! Obtained 1000 equipment points, item points, ability points, and summoning points each!"

"Ding! Task 2 activated!"

Instance World: Hayate the Combat Butler!

Instance Task: Clearance!

Task 1: Enter Hakuhou Academy and become a high school student at Hakuhou Academy;

Task Reward: 1000 equipment points, item points, ability points, and summoning points each;

Task 2: Slay the Ghost Leader located in the old school building of Hakuhou Academy;

Task Reward: 10,000 equipment points, item points, ability points, and summoning points each;

Task 3: Not activated;

As he received the document, a series of sounds rang in Wu Yan's mind. On the surface, Wu Yan tried to look surprised, while his consciousness was immersed in the content that had sounded.

Ghost Leader? What is that thing? Is there such a thing in the old school building of Hakuhou Academy?

Why wasn't it mentioned in the original story? With so many people at Hakuhou Academy, hasn't anyone discovered that there's a ghost in the old school building?

Suddenly, Wu Yan remembered that there seemed to have been a scene related to such a thing in the original story. One night, Ayasaki Hayate accidentally entered the old school building to retrieve something that Sanjouin Nagi had left at school, and then, along with Hinagiku, who came looking for him, they were chased by a ghost.

But, in fact, this so-called ghost was just a dead object controlled by a spell by Izumi Ritsunomiya, the genius exorcist from the Ritsunomiya family, to scare away Ayasaki Hayate and Hinagiku. Well, although she made a mistake in the end and was seen through by Ayasaki Hayate, Ayasaki Hayate didn't expose Izumi Ritsunomiya, but ran away with Hinagiku.

The reason Izuminokami Satsuki tried to scare away Ayasaki Hayate and Hinagiku was to prevent the upcoming exorcism ritual from accidentally injuring them!

Could it be that the spirit Izuminomiya Izumi exorcised in the old school building in the original story was this so-called Ghost Leader?

Alas, why isn't it a mission to pick up girls? All the other protagonists have such missions
