Renjun is a 2nd year college who's taking the course of engineering. He's doing good in class just like everyone else. What—or who keeps him motivated? His Mathematics professor.

He goes to school early just to see him first in the morning. He gets upset whenever he's late and the bell already rang. There's this one instance where he went to school so early that the gates were still closed and he had to wait outside.

Just like today, he enters the school gate early, greeting the guards with a wide smile on his face.

He walks to the pathwalk and sits on the long bench, his backpack clinging on his shoulder and his feet swinging above the ground.

Suddenly, his smile grew wider when the person he's been waiting finally arrives. He gets off and approaches him, greeting him politely.

"Good morning, Mr. Lee!" he says in an enthusiastic tone in his voice.

Mr. Lee turns to him and smiles back, "Good morning, Renjun-ssi. You're early?"

"I'm always early." He grins. "Let me carry your bag to the faculty room."

"Sure." Mr. Lee hands him his bag and he happily grabs it, carrying it so careful.

They both walk to the faculty room and Mr. Lee opens the door, the breeze of the air conditioner comes out of the room.

Aside from Mr. Lee, one of the best things Renjun likes in the faculty room is the cool breeze coming from the air conditioner.

They enter the room and walk to Science department, where Mr. Lee's spot is located. He's both a Biology and a Mathematics professor.

When they arrive to Mr. Lee's chair, Renjun gently places his bag to his desk and bows 90 degrees angle.

"Thank you, Renjun-ssi. You can go to your room now, the bell will go off soon." Renjun melts whenever his crush smiles at him. He has such a pretty smile.

He can't brush his smiles off his face. "Okay, Mr. Lee. See you later at class!" He's so thankful Mr. Lee is their section's adviser.

"Sure. See you later."

Renjun waves at him and hesitantly leaves the faculty room. He pouts when he's already outside. He sighs and finally walks to his classroom.

~~~

It's their math period. Finally, his favorite class ever.

His sits properly when Mr. Lee enters their classroom. He smiles widely as he follows him through his eyes. He's thankful he's sitting in front so he can admire him even more.

"Good afternoon, class!"

"Good afternoon, Mr. Lee!"

Renjun watches as Mr. Lee prepares the things he needs to use for today's class. He picks up a black marker from his bag and opens its cap.

"Everyone, today, we will be talking about the derivative of functions. Are you ready?"

"Yes, sir!"

Of course, Renjun is ready. Always ready.

"All right, let's start!"

He puts his elbow on his desk and rests his cheek on his palm, staring at the way Mr. Lee writes equation on the board.

He's always fascinated at his professor's way of writing and teaching. It's so neat and you can tell he's always taking his time for the students to understand the equation and its solution.

Although he doesn't understand Maths, he's still trying his best. Sometimes, he copies whatever Mr. Lee writes on the board. And then he tries to review them until he understands them, which doesn't happen often.

Currently, while he's copying all the writings on the board, Mr. Lee asks, "Do you understand or do I have to provide another example?"

Someone at the back replies, "Another example, sir, please."

Mr. Lee nods and grabs his marker eraser. "Can I erase them?"

"No, not yet, sir!" Renjun suddenly yells, and when he realizes it, he presses his lips together and tries not to look at his professor.

Mr. Lee looks at him and laughs softly, "Alright, let's wait for Mr. Huang."

He blushes when his crush mentioned his name. He chews his bottom lip as he finishes copying what's on the board.

"Okay, sir, I'm finished. Thank you." he shyly says.

"You're welcome." Mr. Lee smiles at him again and Renjun feels like fainting right here and right now.

Soon, the bell rings and he pouts, sighing silently while resting his back on the chair.

"We will continue the discussion tomorrow, everyone. Class dismissed! You may take your lunch now."

"Bye, sir!"

"Thank you, sir!"

Renjun watches Mr. Lee puts away all his things into his bag. When he finishes, he clings his bag onto his shoulder. He turns around and walks towards the door.

He's still staring at him and when Mr. Lee walks pass him, their eyes meet. He couldn't breathe, Mr. Lee even smiles at him. He really wants to faint.

The professor finally exits the room and he exhales heavily. "Fuck." he mumbles under his breath, "He's so handsome!"

~~~

From Renjun's perspective, Mr. Lee sits at the table with his co-professors. He places his lunch on the table while talking to them, he can see his beautiful smiles and laughs even from afar.

He didn't realize his friend slid a bottle of water in front of him. "Hey, Renjun!"

"Huh?" He looks down at the bottle and then to his friend. "What's this for?"

"You're so thirsty!" Jaemin laughs and he only shoots him a death glare.

He then pouts and takes the bottle of water anyway, opening the lid to drink. When he puts it down, he sighs. "I just hope there's chance we can be together."

"What the fuck!" His friend exclaims, "Renjun, you can't."

"What if I confess to him?"

"Even if you do that, you still can't be together because you're a student and he's a professor."

He knows that. And it hurts.

He looks at Mr. Lee with a bitter smile and then to his friend again. "I'd still confess to get this out of my chest."

Jaemin smiles back and nods, "Okay, Renjun."

~~~

So, after school, he goes to Mr. Lee's last class and waits for him to finish.

"Class dismissed! See you on Biology laboratory tomorrow, everyone." The professor announces and finally exits the room.

"Mr. Lee!"

He notices Renjun and stops. "Renjun-ssi, is there anything I can help?"

Renjun sighs heavily, fidgetting on his fingers. "Can we talk, sir?"

"Sure, come with me at the faculty—"

"No, like, somewhere private. Perhaps, at the garden?" He bites on his lower lip. His heart is beating so fast due to anxiousness.

Mr. Lee looks at him confusedly, forehead creasing. Nonetheless, he nods. "Okay. Let's go."

They both walk to the garden and Renjun feels his blood rushing through his face. He looks up at him and, damn, he looks so handsome.

Mr. Lee caught him staring at him and chuckles, "Something on my face?"

"Uh," He shakes his head eagerly, "No, sir."

"We're here."

They enter the garden and sit on the bench nearby the tulips.

Renjun leans his back on the backrest and plays with this fingers once again. The atmosphere is a bit awkward and he feels so embarrassed to even ask him to talk to him privately.

Renjun, you're stupid.

"Renjun-ssi," He hears his name and turns to his Math professor. "What are we going to talk about? Do you have any concerns regarding our lesson earlier?"

"Uhm, that's one thing, sir. But I have something else to say." he says shyly, looking down at his hands.

"What is it, then?"

He chews on the inside of his cheek and manages to look up at Mr. Lee again. Oh, he's really handsome, I blush everytime I look at him. "Sir?" he begins and the professor just raises an eyebrow. "I... I like you. I like you, Mr. Lee Donghyuck."

Donghyuck blinks and just stares at his student. He chuckles and speaks, "You're the only student who had the confident to confess to his crush on a professor."

Renjun gulps and looks away. "Sorry, sir. I've been crushing on you since I was a freshman."

Donghyuck nods, "I appreaciate your liking to me, Renjun-ssi. I understand, students tend to have a crush on their professors. That's fine, it's normal." He ruffles the younger's hair and laughs softly. "We can be friends, though. You can call me Donghyuck when we aren't in class."

Renjun looks anywhere but Donghyuck and doesn't reply. The older just smiles and taps his shoulder. "Renjun-ssi?"

He finally looks at him, at his eyes and he feels like he wants to cry. "I understand, sir—I mean, Donghyuck. Thank you."

"Renjun-ssi, it's okay." The older startles a bit when the younger suddenly hugs him. He hugs him back and rubs his back gently.

He finally pulls away and smiles slightly. "I'm fine. Can you perhaps teach me our lesson earlier? I'm a bit confused."

"Of course! Shall we go to your place or mine?"

"Your place, Donghyuck." Renjun sighs.

Donghyuck nods, "Sure. Let's go?"

"Let's go."

As they exit the garden, he secretly wipes the tears off his eyes and smiles before looking up at his handsome crush.
