Wilbur's POV 

I made my way down the quiet hallways, I was always pretty lonely in the castle other than having the company of the guards and maids. Maybe I should invite my friends here, it's been a while since I've invited them due to all the training that needed to be done. 

I reached the front of the library and was let in by the guards, I walked through the countless isles of books and saw Mr.Halo sitting at our usual spot by the window. "Oh, good morning Wil!" Mr.Halo greeted noticing me, "Good morning Mr.Halo." I greet back sitting down on the chair opposite his. 

"I told you Wil, just call me Bad, we're in private after all." Bad sighed, his tail swishing from side to side behind him. 

Bad was half-devil and half-angel, I know that only royals are the only ones usually born hybrids but people outside of the royal blood have a chance to be born a hybrid. His hair, skin, horns, and tail, are all black, and the halo floating above his head was white with a slightly yellow shine. He always wore a black hoodie that had red edges to cover up his horns cause he gets slightly nervous when his horns can be seen by people he doesn't trust just yet. Despite being half-devil and half-angel, he doesn't have any wings. The most unique thing about him in my opinion was his purely white eyes.

"Right, sorry, not really used to it." I chuckled nervously, "That's fine, in a couple of days your about to become king so congratulations! And also happy birthday!" He said happily, "Thank you, Bad." I thanked him, "Anyways, let's get on with your lesson for today..." 

~*~*~*~

It's been 2 hours. 2 hours of Bad asking me questions and me answering those questions, I was honestly surprised I didn't get any of the questions wrong. "Alright, done!" Bad exclaimed, closing the book he had in his hands. "I'm surprised you didn't get anything wrong." 

"Same here." I sighed putting my face in my hands. "Well, it's about 10 right now so you have a lot of free time till the party tonight." Bad said checking the time, I hummed looking outside the window. A figure outside caught my attention, Techno was sparring with Sam. I always wondered what it feels like to do that every day, I spar with Techno every week but it was only for some time because my father always brings me back inside to continue my studies. 

I sighed staring at Techno who was winning against Sam, "You okay Wil?" Bad spoke up, I turned my head towards him. "Yeah, just thinking." "I know what your thinking Wil, what your father does to you is terrible but after you get crowned king you'll be free." Bad said trying to cheer me up, it did work a bit. 

"Thanks, Bad, I should get going now." I grabbed my notebook and stood up, "Thanks Bad." I thanked, Bad smiled. "Anytime! You're gonna be a great king Wil." I gave him a fake smile and walked out of the library. 

I don't wanna be king, I'm way too young, no other king has ever been crowned at age 17. I wanna be a musician, I wanna play music and write songs, not be a stupid king. I suddenly remember the words my father spoke to me that day. 

*Flashback*

Third Person POV

"DAD, I DON'T WANT TO BE KING! I WANNA BE A MUSICIAN, I WANNA PLAY MUSIC!" A young 12-year-old Wilbur cried. 

"I don't care what you want to be, you will be king and that is final." Philza scoffed, Wilbur sniffled. "THEN HOW COME TECHNO CAN BE A KNIGHT?! HOW COME HE CAN BE ANYTHING HE WANTS YET I HAVE TO BE KING!?" 

"It's because he has the skill, and he has the talent. His role is perfect for a knight." Philza explained making hand gestures, "You don't have that, that's why you're going to be the Crowned Prince. If Techno doesn't want to be king, then so be it." 

"WHAT ABOUT ME?! DO YOU NOT THINK OF ME!? WHY DO YOU FAVOR TECHNO SO MUCH BUT NOT ME?! YOU'RE BREAKING THE KINGDOMS LAW CAUSE-" Wilbur got cut off by a slap from Philza, "SILENCE!" 

Wilbur stared up at his father in shock and fear, "I had enough of your screaming, go to your room." Philza ordered, he turned around and left with a "Tch." 

Wilbur wasted no time and ran back to his room as soon as Phil left. He rushed into his room and shut the door, his back against it. He sobbed as he slid down the door slowly, he cupped his cheek and hissed at the pain. He grabbed his crown and threw it across the room, "Why me, why did I have to be so talentless and stupid." He whispered curling into a ball, sobbing into his knees. 

*End of flashback*

Wilbur's POV

I frowned and tear up slightly at the memory, I shake my head and calm myself. I was already in front of my room, I sighed and walked inside. I place my notebook inside the drawer of my bedside table and sit on the bed, my leg brushes against something causing me to look at what it was. 

The guitar that I placed there this morning, I had nothing else to do so I picked up the guitar. 

I brush my hand against the strings and smiled, I started to strum some chords that I remembered and got the hang of playing the guitar again. Then I started to play a song that I wrote around a year ago, hearing the notes being played was music to my ears. I started by humming to the song but ended up singing a song I wrote called Soldier, Poet, King. 

There will come a soldier
Who carries a mighty sword
He will tear your city down
Oh lei, oh lai, oh, Lord
Oh lei, oh lai, oh lei, oh, Lord
He will tear your city down
Oh lei, oh lai, oh lei, oh, Lord

There will come a poet
Whose weapon is His word
He will slay you with His tongue
Oh lei, oh lai, oh, Lord
Oh lei, oh lai, oh lei, oh, Lord
He will slay you with His tongue
Oh lei, oh lai, oh, Lord

There will come a ruler
Whose brow is laid in thorn
Smeared with oil like David's boy
Oh lei, oh lai, oh, Lord
Oh lei, oh lai, oh lei, oh, Lord
Smeared with oil like David's boy
Oh lei, oh lai, oh, Lord

Oh lei, oh lai, oh lei, oh, Lord
He will tear your city down, oh lei, oh lai
Ohh

Oh lei, oh lai, oh lei, oh lai, oh
Oh lei, oh lai, oh lei, oh lai, oh

Oh lei, oh lai, oh lei, oh lai
Oh lei, oh lai, oh lei, oh lai, oh

I finished the song with some extra notes before strumming one last chord and ending it. 

"You played just like how I remembered all those years ago." A voice chuckled, I looked up to see Techno leaning on my door. "You left your door open, I heard you singing and went to check it out." 

"Oh, I must have forgotten to close it." I scratched the back of my neck, "What's it about?" Techno asks, "Well, I wrote it about our family. You're the soldier,  I'm the poet, and father and mother are the rulers." 

"It's a great song." He complimented, "Thanks." I smiled. "You're really talented, shame that dad won't let you become a musician." Techno shrugged, "Yeah, you should go and freshen up." Techno let out a hum and left the room. 

It was 10 right now and I'm kinda lonely so I decided to invite my friends to the castle for some company.
