Is it right to love an ancient Prince? [Fantasy BL]

The day I fall

"Pooofffff!!!"

A black smoke covered the whole face of Law. He accidentally dropped 2 mL of Hydrogen Peroxide (H2O2) instead of water (H2O) in the beaker that made their experiment explode.

"What have you done?!" Ren can't helped but to look horrified knowing that the solution that he pulled an all-nighter to make was now gone.

"Bro! I'm so sorry I swear I followed the manual. Also, can you be concerned with my face first?" Law argued.

"It was supposed to be 2 mL H2O not 2 mL H2O2! Besides, we have to submit this tomorrow. I deprived myself of sleep for this." He was frustrated but took a deep breath. "Let me see your face." Ren touched Law's face and look at him sternly. "What the heck. You look like an idiot version of Einstein. Haha. Wash your face with running water and mild soap for fifteen minutes and you should be okay."

Law immediately went to the washroom to wash his face while Ren remained at the Lab table with black lines in his face while staring at their ruined formula. Tomorrow is the deadline and it took them 24 hours at most preparing this solution.

Ren and Law are freshmen Engineering students at a top university in their country. They knew each other at the freshmen orientation together with the Fine Art student Troy. The three of them have been close since then and they have been quietly popular among freshmen as well because of their good looks.

Meanwhile in the mighty Kingdom of Bellestia...

"You're highness, the green ogres are attacking the west farm again." A soldier urgently alerted the King.

"Call my son Lucas and let him get rid of these. At once!" The King commanded.

Prince Lucas heard the summons and went to the West farms immediately. He and four of his chosen personal knights fought the green ogres that always try to attack the farms for food. They have easily slain all these "pests", as the prince called it. The farmers were amazed as they have finished the problem with such ease as if it was just mosquitoes.

"Prince Lucas! Thanks for saving us." One of the farmers in the crowd shouted.

"Pheww... It was nothing. It's an insult to my powers if I even shed a sweat to those things." Prince Lucas boastfully muttered.

The Prince is famous for being a strong warrior of their Kingdom. He is about six feet tall, has a lean muscular  body and a very handsome face. It is just that some fellows at the Kingdom described him as rude, boastful, ruthless, can be easily angered and has a very low social skill. Although the King, his father, sees him as a reliable son and worthy of the throne in the future.

"Lucas, the King wants to see you as soon as we are over here." Lord Greg, one of his knights told him.

As they went to the Kingdom, they immediately went to the throne room where his mother, father and their Kingdom's high mage are there.

"Yohohoho! My sweet Lulu is here." Queen Celia was very happy to see his son. She is said to be the most beautiful lady in the whole kingdom. She is always cheerful and always try to baby his children even if they are adults now.

Prince Lucas blushed when he heard the word Lulubut ignored her mother. "Father, you called me."

"Yes, son. Old Arthur here has a very important announcement for everyone of us and the safety of the Kingdom is at stake here. Old Arthur if you may."

"Yes, my Lord. I am here to announce that the Fates warned us of the rise of the Demon Lord in the south. He will turn the whole Kingdom and the whole planet into darkness unless he is subdued. Only a hero from another world is destined to defeat him." Old Arthur said loudly.
