My first Fanfic, please forgive my grammatical errors. Constructive feedback is appreciated.
This fanfic is a continuation from The Ojou-sama's magnificent day off. The prologue is a brief summary of it just in case you have not read it.

Prologue

The year 2095, November 2nd

Itsuwa Moi and Itsuwa Hirofumi, one of the 13 internationally acknowledged Strategic Class Magicians, visited Mayumi at the Saegusa residence before heading to the frontlines. They wanted insight into their enemy's magic from Mayumi. Mayumi, having stayed on the rear during most of the fight, recommended that they turn to Mari, Kei, Kanon and Katsuto for insights. After Moi and Hirofumi left, Koichi asked Mayumi to set up a meeting with the Shiba siblings.

Chapter 1

"Tatsuya-kun, Miyuki-chan, follow me for a moment," Mayumi said and exited the Student Council room.

"My father would like to invite both of you to the Saegusa residence for dinner tomorrow. Will you be able to make it?"

"Is it related to my magic?" Tatsuya asked in a rather serious tone.

Mayumi pressed her lips and shook her head. She had made sure everyone who had witnessed Tatsuya's magic keep a tight seal on their lips so it was impossible for her father to have heard of Tatsuya's unique magic.

Tatsuya had his doubts on whether Saegusa Koichi had information on his magic. Of course, he ruled out the possibility that Mayumi had backstabbed him, but rather he knew of Koichi's infamous reputation to acquire even the best-kept secret. Either way, it was an invitation that he was in no position to decline. After all, how could he reject an invitation from the head of the Saegusa family?

Still troubled from Mayumi's invitation, Tatsuya let out a sigh and sat in front of his workstation.

"Onii-sama, are you troubled by the fact that Saegusa-sama might have smelled something fishy regarding your identity?" Miyuki asked Tatsuya as she served him a cup of coffee.

"As expected, I can't hide anything from my Miyuki. Saegusa-sama most likely suspects that I am not a regular high school student due to my combat and CAD engineering abilities. He will most likely use the dinner as a platform to try to uncover more about me."

"Onii-sama, although they are the Saegusa, they will most likely not know about any of your identities. ...Your identities are being safeguarded by the Yotsuba after all"

"Right, do not worry about it Miyuki" Tatsuya replied with a forced smile.

Miyuki quickly left Tatsuya, knowing that she said the wrong thing.

Worried that Miyuki will blame herself for bringing up the Yotsuba in front of him, he wanted to go after her to comfort her, but for once he felt that it was better for him to have some time alone. After all, he needed to think about how he will face Saegusa Koichi tomorrow night.

Letting out yet another sigh, Tatsuya drank the coffee Miyuki brewed for him and allowed his brain to go to work.

(Scene change)

The following evening after school, Tatsuya dressed in a formal suit while Mayumi put on a gown for the dinner. Although the siblings made an effort to arrive ahead of time, it was Mayumi who was waiting for them at the reception.

"I hope we didn't make you wait too long, senpai" Tatsuya said as he and Miyuki approached Mayumi.

For the first time, Tatsuya saw Mayumi in formal attire. His eyes unwittingly darted all across Mayumi to take in the full spectrum of beauty standing in front of him.
