Mistake||Namjin

Four

Once lunch time came around, Jin went to his locker to grab his lunch, Jimin had followed. "I can't believe you actually live with him, he's so hot." Jimin said. "But I won't take him from you. I have my eye on someone already." Jimin swooned.

Jin felt someone squeeze his sides, causing him to jump and squeal. Jin turned around to Namjoon and Aeri who were laughing at him. "Why would you do that!" Jin whined. "Because, it's funny." Namjoon laughed.

"Come on, all my friends are probably waiting on us." He said. Jin nodded and grabbed his lunch bag, him and Jimin walking behind Namjoon and Aeri.

They walked into the lunchroom and plenty of Freshmen girl's heads turned of course. Namjoon was an eye catcher at their school among the guys. The main reason he was popular too.

Once they reached the table, Namjoon introduced Jin to everyone. "He's your stepbrother now?" One asked. He had long fluffy brown hair and a baby face. "Yeah, an you guys are gonna be friends with him and his friend whether you like it or not." Namjoon said.

Jimin met eyes with Yoongi, who rolled his eyes, Jimin blushing madly. Jin sat next to Namjoon, Aeri on the other side of Namjoon. Jimin sat next to Jin, and on the other side of Jimin was Yoongi, how awkward.

"I'm Jungkook." The baby-faced one said. "Hello." Jin said shyly, Namjoon discreetly smiling to himself at his cute habit of being shy anytime he met someone new. 

"You already know me." Yoongi said dryly. "I'm Hoseok!" One smiled brightly and waved from the other side of the table. "I'm Taehyung!" The boy waved. He was sitting next to Hoseok.

"I'm Ten!" "I'm Vernon." "I'm Jackson!" "I'm Mark!" Jin didn't know how to keep up with all of Namjoon's friends, he had so many. "Nice to meet you all." Jin smiled warmly.

They all began talking with each other, Namjoon speaking so highly of his birthday party that was coming up soon. "I throw huge parties every year, you're gonna have so much fun." Namjoon said to Jin who nodded with a small smile.

"How come your being so shy, hm?" Namjoon chuckled, his beautiful dimples showing. "I'm j-just not used to being with so many people." Jin looked down at his lap, hardly able to look into Namjoon's eyes.

"We'll get used to it, these are your friends now too." Namjoon spoke quietly, comforting in a way to Jin.

...
After school, Namjoon took Jin to his car. "You can sit up front, Aeri is going to hang out with her friends." Namjoon said and Jin nodded.

He sat in the passenger seat and sighed, tired from the first day. "You alright?" Namjoon asked, looking at him. "Yeah." Jin said. "Okay, tell me if something's bothering you." Namjoon said, resting his free hand in Jin's thigh, Jin's face warming up very quickly.

Namjoon noticed and smirked as he drove home, Jin slowly grabbing Namjoon's hand and taking it off. "You're really touchy." Jin murmured. "I thought you wouldn't mind." Namjoon said.

Do brothers usually do this?! Jin thought. He'd never had a brother before so he didn't know or wasn't used to the idea of skin-ship. "Umm, I guess I have to get used to it." Jin said.

They arrived home, neither of their parents home. "So both of our parents work late, huh?" Namjoon said. "Yeah, my mom isn't usually home until 11." Jin sighed.

He went upstairs to his bedroom and set his backpack down. Namjoon knocked on the door a few minutes later.

"Come in!" Jin called and Namjoon entered. Jin felt his mouth watering as he looked at him, Namjoon wearing a tight fitting white t-shirt and grey sweatpants.
