Chapter 14: Formula of Love

[Pan here! And here is the final chapter of this book! It was fun writing this! I hope you guys loved all the math and sciences references I left at all the chapters. It was fun reading textbooks again just to check if what I wrote is scientifically correct. Until next time!]

~Chapter I: Introduction - 10 days before proposal~

"So what's the plan, Y/n?" Jeongyeon asked as she and Y/n reached the mall. Her being married, Y/n thought it would be nice to have her advice when it comes to picking the ring.

"Well, you just gotta help me find a ring. I plan to talk to the others with this as well." Y/n said as the two went inside of the mall. It was a Wednesday, the dead center of the week. There weren't many people but it's Seoul, there were foreigners scattered around with still a substantial amount of native Koreans even though it was a normal day for the country.

"Can you go to the jewelry store first? I'm gonna go to the flower store across the mall. Thank God even in the bustling and industrialized streets of Seoul there's still a small flower shop inside of it." Y/n said as Jeongyeon chuckled and nodded in approval.

Y/n exited the mall and crossed the street, a small flower shop in the midst of tall buildings. Y/n opened the door as the chimes melodiously sounded at his entrance, the shopkeeper looked at Y/n and realized who it was.

"Y/n! It's been a while." The shopkeeper said as he raised his hand and waved at Y/n.

"It's been a while, Mr. Park." Y/n said as he bowed as a sign of respect.

"That was a long time ago, Y/n. I'm not your high school biology teacher anymore. Call me Jin-young." He said as Y/n smiled.

"Mr. Jin-young. You're still older than me." Y/n chuckled.

Park Jin-young, a former teacher of Y/n. Y/n was never Jin-young's best student, Y/n never really liked biology but he made it through. After retiring, he opened up a flower shop which has been flourishing ever since. Y/n has kept in contact with his biology teacher, especially when Jin-young had a relative who went to Y/n's infamous calculus class.

"And here I thought you'd give me the chance to feel younger. Anyways, what can I do for you?" Jin-young complained and asked his former student.

"I'm in a relationship, Mr. Jin-young and I plan to propose to her. Prepare me the best bouquet you have, please." Y/n said as Jin-young clapped.

"My, my, if you told me that you're in a relationship when you were in high school, no one in the faculty would ever believe you. But you're all grown up now. I'll prepare it for you, even for free!" Jin-young said as he patted Y/n on his shoulder.

"I can't let you do it for free, Y'know? At least let me pay half of it." Y/n said as he scratched his head.

"Fine, even though I'm willing to do it for free. When will you need it?"

"I'll get it 10 days from now, probably earlier than this time of day. I'm counting on you, mr. Jin-young. I don't know much about flowers but I know you're the best at it. I need to go now though, I have a friend waiting for me at the mall." Y/n said as he gave his former teacher a hug. The two said their farewells and Y/n made his way back to Jeongyeon.

Y/n met up with Jeongyeon who was already looking at some engagement rings.

"Hey, Jeongyeon." Y/n said as he entered the shop, getting the attention of Jeongyeon.

"Look at these rings, Y/n. I think Nayeon would love any one of these." She said as Y/n went nearer. Y/n saw the assortment of rings Jeongyeon recommended, it was all beautiful but one caught Y/n's eye. It was an engagement ring with a slim ring and a somewhat sky-blue gemstone on top. It was simple but it looked beautiful.
