Quantum Entanglement Love (Series 1)

Mun Sara was sitting at her desk in her room, the dim light revealing a frown and anxiety on her face. She was staring at the heart-shaped equation that Minjun had solved. A nagging feeling in her gut had bothered her ever since she noticed how much Minjun seemed to enjoy every gesture she made for him. She sighed repeatedly, realizing that Minjin might know Minjun better than she had expected. Additionally, she knew Minjin had secretly completed every senior's calculus assignment. For the past few days, she had observed Minjin easily solving those problems. 

Sitting in front of her laptop, she suddenly wanted to search for Park Minjin. To her surprise, the results appeared in English. However, her eyes widened in shock when she noticed a headline stating that Park Minjin was recognized across America for her intelligence in physics, boasting an IQ that surpassed Einstein's. Her heart began to pound, and a wave of pain hit her as the realization sank in. 

Minjin and Minjun shared a bond that was deeper than friendship. She felt conflicted about whether to be upset with Minjin for not being truthful, especially since Minjun had openly expressed his feelings. Minjun still wanted her, which explained why he had been turning down other girls over the past few years while they were friends. 

Another realization struck her, and she lowered her head to gaze at the heart-shaped equation. Minjin might have felt the same way about Minjun. She swallowed hard, pressing her forehead with an ache in her chest. 

She determined that Minjun should not discover that Minjin had returned to Korea. However, she wondered if she could keep this secret forever, especially since Minjun was also her friend.

During lunch in the cafeteria, Bang Eun-kyung overheard whispers about the music club that piqued his curiosity. Students were buzzing about a sophomore and the club's activities. 

When he reached the table where Minjun and Mun Sara were sitting, he couldn't help but mention it. "Everyone seems to be joining the music club," he remarked. 

"Yeah, I noticed that last night," Minjun replied, seemingly unimpressed. 

"Really?" Bang Eun-kyung asked, intrigued. 

Seeing Minjun's reaction, Bang Eun-kyung decided to investigate further. Throughout the day, he approached various students about the music club. Some students were evasive or ignored him, which only fueled his suspicion. 

After classes, Bang Eun-kyung decided to wait in the classroom for a few hours, hoping to gather more information. When he noticed a light in the music room, he approached it. Just as he was about to open the door, a group of students arrived. 

"Bang Eun-kyung? Are you also going to have Minjin help you with your assignment?" one of the students asked. 

Caught off guard, Bang Eun-kyung stammered, "Y-yes! I am." 

The student knocked on the door using a specific code. When Choi Ye-joon opened it, he looked surprised to see Bang Eun-kyung. 

"Are you here to ask Minjin for help with your assignment?" Choi Ye-joon asked. 

Bang Eun-kyung nodded, and his curiosity about who Minjin was grew even stronger. He was eager to learn more about the mysterious figure behind the academic assistance and the secretive activities of the music club. 

As Bang Eun-kyung entered the room, he noticed a crowd gathered around a girl with a boyish haircut who was intently working on a complex calculus equation. To his amazement, Minjin solved the problem with remarkable ease. 

"Boya, who are you?" Bang Eun-kyung asked, bewildered by the scene. 

The students surrounding Minjin turned their attention to him, and one of them spoke up. "Isn't she such a genius?" the student said. 

"Park Minjin?" Bang Eun-kyung asked, his voice filled with a mix of awe and confusion. 

The room buzzed with excitement and curiosity as Bang Eun-kyung processed this revelation. 

### 

Minjun, accompanied by Mun Sara, the class representative, went to the teacher's room to submit the collected notebooks. As they approached the desk, Minjun overheard a group of teachers discussing the calculus scores of some senior students. The teachers appeared both confused and surprised by the sudden improvement in the student's performance. 

Minjun listened intently to the hushed conversation, intrigued by what could have caused this unexpected change. Suddenly, Mun Sara called out to him, breaking his concentration and pulling his attention away from the teachers' discussion. He turned to face her, momentarily distracted from the mysterious topic. 

### 

After their class, Bang Eun-kyung happily stood up, excited to head out. Before he could, Minjun called out, "Ya, Let's go home." 

Bang Eun-kyung hesitated and glanced back over his shoulder. "Um, n-no, the coach wants to talk to me," he replied, stammering slightly before quickly exiting. 

As he left, Mun Sara approached Minjun with a smile. "I'll come with you," she offered. 

Minjun nodded in agreement. 

Later, Bang Eun-kyung cautiously approached the music club room, where several students were waiting for Minjin. When Minjin arrived with Lee Deji, the students parted, creating a path for her to the seat that had been prepared. A student handed her a bottle of water, which she gratefully accepted. After taking a few sips, she looked up. 

"So, who's going first?" Minjin asked, her voice calm. 

She briefly studied the topics and equations in a calculus book before she started explaining and answering questions with ease. Bang Eun-kyung, standing at the back, watched her in amazement. "Wow, you're even smarter than Minjun," he said in awe. 

Minjin chuckled at the compliment and shook her head. "No, he's smart in his own way," she replied. 

"Do you know Minjun?" Bang Eun-Kyung asked. 

"Who doesn't know him?" Minjin said as she focused on solving the calculus notes. 

Bang Eun-Kyung nodded. "Yeah, you have a point."
