At the Loud house, Leni was about to leave the house when she felt somebody pulling her dress. She turned around, then looked down to see it was Lisa, who was blushing and looking away. "Oh hi Lisa, what is it?" she said as she crouched to Lisa's height.

"I, and it said that people with opposite personalities are more likely to grow friendly with each other." the little genius responded. "So, I was wondering if you'd like to hang out, to prove that even, we can be the best of friends."

The teenager tilted her head, no doubt out of utter confusion.

And soon enough, Lisa clarified: "I wanted to know if you'd like me to accompany you to the mall today."

Leni immediately screamed in joy, and wordlessly grabbed Lisa and brought her to the mall. Once they got to the building, Lisa immediately caught the attention of the mall cops.

"Who is this little kid you brought with you today, Leni?" the cop asked, giving Lisa a quick check.

"These people know you?" Lisa asked, turning to her sister.

"Of course, I come here so often we're practically friends!" the fashionista eagerly answered before tightly hugging her sister and explaining, "This is my little sister, Lisa. She's a genius."

"She looks the part, at least." the cop allowed the girls to go in. "Okay, come in."

And so, the duo went deeper into the mall, with Lisa holding Leni's hand as they looked around. However, the attention they got from the nearby mall visitors soon made Lisa uncomfortable, making her hold her sister's dress.

"Is something wrong, sis?" Leni asked, noticing Lisa's mood.

"I'm...not used to this kind of attention." Lisa replied, looking at the ground.

Seeing her sister wasn't comfortable, Leni stopped, crouched down and gave Lisa a trustworthy look as she gave her some advice: "Listen, how about I take you back home, and when I go do something you're more comfortable with, you hang out with me again?"

Lisa firmly looked at Leni, and blushed as she nervously nodded and followed her out of the mall.

Back at the house, a couple hours later...

Leni went back inside into the house, carrying a pink bag with her. "Lisa, I'm hooome!" she shouted as she strolled to her sister, who was sitting at the couch. "How's my little sister doing? Are you feeling better?"

"Much better, thanks." Lisa answered.

"Good, 'cause I got a gift for you!" Leni reached for her bag, and as familiar music played, the teenager slowly took out the content until she took out diamond-shaped glasses. "Ta-ta-ta-ta! Fashion glasses!"

Lisa took the glasses and gave them a quick look before saying, with a smile, "Thanks, Leni."

"I know you prefer your normal glasses but-" a second later, the teen realized what the girl said. "Wait, what?"

By the time she turned to the genius, she had swapped her normal glasses for the fashion glasses she bought. "I'll go boast about these to the rest of the family." Lisa stated.

And so, the little genius started to go upstairs and smiled as she heard Leni rejoice downstairs. Looking at her sister one more time, Lisa put on a smile before finally going to the second floor, leaving behind the joyful Leni to rejoice.
