Yuuki bought two songs and some primary musical instrument proficiency skills. He went to the keyboard and beat maker at the same time. He picked the popular kid song in this world, only he rearranged it to become more interesting.

He could see that there was some song that was similar to his past world, though, it was different but there were some similarities with the song in his past world.

Toyomi looked at him and asked, "Can you play the keyboard?"

Yuuki nodded, "Well, I can but it is just normal."

Toyomi looked at him with interest since her little sister had won the piano competition before. She wanted to hear what kind of song he would play.

Hina had already taken the maracas and shook it with vigor.

"Ahem, please listen to 'Twinkle Twinkle Little Start'," Yuuki said.

Toyomi raised her eyebrow since she had never heard the title of this song. She looked at the screen and it was the song that she had heard when she was a child but somehow it was different. She saw him rearrange the song slowly.

Yuuki was ready to sing but he needed to check the keyboard and beat maker. His skill was average at least when he played the musical instrument but he had confidence in his singing skill since he had always sung in the bathroom when he took a bath. He looked at Hina and said, "Hina, why don't we sing together?"

"Yes, Oi-tan!!" Hina nodded and walked toward him.

Yuuki picked her up and told her to follow him singing.

Hina nodded and gave him a thumbs up.

"Then we will start in 1, 2, 3..." Yuuki said and sang, "Twinkle twinkle little star..."

"Twinkle twinkle little start..." Hina also sang together with him. She felt that she had heard this song but somehow it was different from what she had sung before but this was more interesting and fun at the same time. She was excited and happy at the same time since both of them could sing together.

Yuuki was surprised that he couldn't find 'Twinkle Twinkle Little Star' but rather some song that had the same melody but different lyrics.

Toyomi was amazed at such a simple song yet it was a very beautiful song. She looked at both nieces and uncle who sang together. She looked at him and felt that it wasn't bad to marry him in the future. She saw her interacting with his nieces with a smile and thought that he would become a good father in the future. She looked at them with a smile and shook the maracas while listening to their song.

"Twinkle, twinkle, little star, how I wonder what you are...."

Hina and Yuuki sang at the same time. He gave some last melody and ended the song. He smiled and asked, "How is it?"

"It is fun, Oi-tan!!" Hina said.

Yuuki nodded, "Are you satisfied?"

Hina thought for a bit and shook her head, "No! Oi-tan still hasn't sung a song for Toyomi-Onee-chan!!"

"Yes, you still haven't sung a song for me," Toyomi said. She wanted him to sing another song this time it wasn't for Hina but for her. She wanted to know how was his feeling for her through the song that he sang today. She had been very nervous yesterday since she had asked him to become her fake fiance. Even though her expression was aloof but it was to hide her nervousness. She didn't want anyone to see her weak side.

Toyomi also had asked her father to give him an appropriate reward to become the leader of their family guild since his status as S-Class Hunter and his appearance on the television yesterday. She knew he was very strong and it was hard to read his emotions. Though she knew that he was very flirty toward her, she wasn't sure whether it was real or not.

Toyomi wasn't naive enough to think that he would accept the agreement without seeing the contract of the guild or even accepted it right away. She also knew that he had a special relationship with Kaoruko.

Compared to her sister who was talented and cute, she was only a small constellation that was very dim in the sky and her sisters were the brightest constellation in the sky. Her only advantages were her beautiful body but that was it. She didn't have any talent or anything. She knew there were still a lot of beautiful girls and women in the world that were better than her. She knew that he could get whenever he wanted as long as he wished for it.

It was understandable that she was worried since he didn't look very serious and it was her woman's instinct that told her that he could leave her anytime. She didn't want to marry anyone else by force and she also couldn't find a perfect candidate for her partner beside him. She wanted him to look at her, or at least very seriously think of her as the best woman out there.

Yuuki didn't know what Toyomi was thinking but when he heard her voice. His instinct told him that there was a trace of worry in her voice even though she hid it quite well. His first impression of her was a woman who could hide everything under that aloof expression. He didn't know whether she couldn't express her emotion well or if she tried to bury everything under that aloof expression.

Yuuki didn't really know well but he knew that he wanted to see more of her emotions. He wanted to open it thoroughly and made her unable to hide her emotion from him. He thought it was a perfect song for that and luckily he had bought it earlier.

"Oi-tan, are you ready?" Hina asked.

Yuuki nodded, "Yes, this song is special for Toyomi...."

Toyomi raised her eyebrow and didn't believe it.

Yuuki took a deep breath and said, "The title of this song is 'Polaris', please listen..."
