"No, all of your answers are wrong again." Soojung commented for the nth time this night after scanning Mark's work and answers for the examples she provided for him. She could hear him sigh for the billionth time tonight. Her eyebrow raised as the male snatched back the sheets of example problems before silently fixating his eyes onto them once again. 

Odd.

She watched him knit his eyebrows together as he focused on working through each of the problems another time. Normally, the male would be asking her for help. At the very least, he would be whining about how it was difficult and would give her puppy eyes to avoid his homework and studying. Rather than that, he was actually quite serious while trying to solve the examples. Mark was typically always a sweet and optimistic person; he would never put up a cold attitude with her.

After watching him stare at the same problem, repeatedly writing and erasing his pencil marks, she just knew he was stumped. "Do you want me to walk you through another example?"

"No. I can do this myself."

She was staying up for him, trying her best to help him, yet he chooses to speak with her this way? Sure, he might've never been this way before, but that doesn't mean she'd let him off the hook. At first, she thought he was just trying to solve things individually before asking for help, but now he's just being absolutely rude. 

Sure, Soojung could simply it up and pretend this night was nothing that bothered her, but no, she refuses to allow that to happen when she put in her effort and time to help him at the latest hours in the night. She was beyond angry with him at this point; she was tired and had no time to be dealing with someone with that kind of attitude.

And so, the girl pushed her chair away from the table, standing up and causing him to raise his head. "I don't know what's wrong wi
