After school, Ren walked through his front door and immediately noticed Leonel's things scattered on the table. He called out, "Hey Leo, what's going on? You look like you're ready to pass out."
Leonel lifted his head and rubbed his eyes. "Hey Ren, I've been trying to study for our final exam, but my brain feels like mush."
Ren chuckled. "Well, lucky for you, I'm an expert at cramming for exams. What do you need help with?"
"I don't even know where to begin," Leonel said, sighing heavily.
"Let's start with math," Ren suggested, picking up Leonel's notebook. "What's been giving you trouble?"
"The formulas, mostly," Leonel admitted. "I just can't seem to remember them all."
Ren flipped through the pages, nodding as he read, "Okay, well, let's go over them one by one. I'll help you remember."
"Thanks, Ren. I really appreciate it," Leonel said gratefully.
