Finally, the song was coming to an end. Niall sighed in relief, before remembering that next was Little White Lies. The blond groaned, that meant he had to get his guitar. Niall could only frown and slowly made his way back to the main stage. But since his knee was not cooperating that well, it could take a while for him to actually get there.

Louis noticed his friend walking back to the stage and also how slow he was going. He realized that Niall had to take some time, so he approached Liam and whispered, "Talk for a bit. Niall's in pain."

Liam's eyes widened. He looked over at Niall and noticed him limping. Liam gave Louis a nod just as Harry sang the last line. Liam looked at Niall one more time before he put on a smile on his face and walked to the front of the stage. When he walked past Harry, he noticed that he was wearing his orange shirt in a different way.

"Harry, you've got something over there. It's humongous." Liam said, referring to Harry's orange shirt. He laughed a little before turning back to the crowd and shouting, "Amsterdam!"

When Liam said that, Niall had finally made it to the stage. He was tired from walking up the steps with his injured knee, so he grabbed hold of a nearby stage part and panted a bit. Paul walked to him with his guitar, and he seemed worried. "You okay, Niall?"

"I didn't know walking was this hard." Niall admitted, still panting. Paul frowned as he turned to Niall's injured knee. "What happened?"

"Hit by a phone. Started acting up again." Niall explained, wincing from the pain.

"Do you need to sit down? The lads could stall for you." Sandy asked the Irish boy. He looked over Niall's shoulder to see the other boys on stage. Liam was talking to the fans, and he was glancing briefly at them both. The guitarist also noticed the other boys doing the same thing, fiddling with their microphones nervously.

"Actually, scratch that. They're already stalling for you." Dan said, giving Niall a smile. The latter shook his head and went to grab his guitar from Paul. "No. There's only two songs left, I can do it."

Paul and the band frowned at that, clearly not on board with his idea. But the adult nodded anyway and helped the blonde put on his guitar. "Alright, but take it slow. And, be careful."

Niall chuckled and flashed the manager a smile. "Louis said the same thing." Paul blinked, before he chuckled too. "Of course he did."

Then, Niall was finally set up and ready to go. Paul made sure that he was comfortable and the guitar was in the right position. "Are you sure you can do this? You can just sit here, you know." Josh suggested to the blonde, looking worried for his friend.

"I don't want to let down the fans. I'll just walk around less." Niall answered, shrugging to the drummer.

"Try not to jump around, Niall." John advised the singer.

"Believe me. I wasn't planning on it, John." Niall chuckled, flashing the guitarist a small smile. John couldn't help but smile back and pat the singer on his shoulder. "Be careful."

Niall nodded before turning back to the crowd. The pain was getting worse by the minute, but it was bearable to him. Liam, who was talking endlessly to the fans, noticed that Niall was finally ready. The blonde gave him a nod, and Liam smiled in relief that Niall could still do the concert. But, he knew that the Irish boy couldn't last long. So, he quickly ended his rambling about Amsterdam and announced their next song.

"And this is Little White Lies, everybody!" He shouted to the crowd, making them scream louder. The music started to play, and the boys started to walk around the stage. Niall stood in place and strummed a few notes before he carefully walked down the stage to join the boys.

Louis approached Liam and they began to walk together. The older boy glanced at Niall worriedly before he focused back on his friend beside him. "Keep an eye on him." he whispered, referring to the blonde behind them.

Liam nodded and said, "Right ahead of ya, mate." Louis gave him a smile and turned back to the fans around them. Liam smiled back, and adjusted his earpiece a little. Then, he began to sing his solo.

Despite the pain on his knee, Niall managed to walk a bit faster than he expected. He wasn't limping like before, so that's a plus. Niall continued to walk across the stage while playing his guitar. The Irish singer stopped at a spot near the front stage, so he could stop putting stress on his knee but still be near the others.

The boys noticed, of course, so they all stood near him so that he won't feel left out. Liam was in the front and interacted with the fans there. Harry was walking on Niall's right, giving a few waves here and there. Louis and Zayn walked around a little, but they were still fairly close to Niall.

Niall walked a few more steps forward and the boys followed. Liam moved to the right side of the stage so that Niall could take the left side. Louis walked closer to Niall so he was beside the lad. Harry and Zayn stayed behind them and then they all continued to sing the song.

After about three minutes, the music finally ended and the song was over. Their next song was Best Song Ever, which was also the last song of the concert. But, Niall was getting exhausted. His knee pain was getting a bit too much, and he really needed to sit down and rest. But, he also needed a few minutes to do that. With that in mind, Niall turned to Louis and gave him the look.

The oldest understood instantly, so he nodded at Niall and began to walk over to Liam. Niall smiled gratefully at him, before he turned around and started walking back to the main stage.

"Liam." Louis said with his microphone, earning the boy's attention. "Niall's hurt his knee, so he wants for you to talk." He pointed his finger to Niall, who was already halfway there.

"Oh, no. Niall's in pain!" Liam said, looking at the blonde. He focused back to the fans around him and smiled. "Alright, let's talk again everybody!"

Louis trusted that Liam could buy Niall some time, so he turned to the main stage and followed his friend. When he passed by Zayn, the Bradford boy started to walk beside him, looking worried. "What happened?" he asked, referring to Niall's knee.

"I don't know, mate." He replied honestly. "But, I'll check on him."

Zayn still looked worried, but he nodded at his older friend and patted his shoulder. "Alright, keep me updated."

"Of course." Louis smiled at him. Zayn did the same thing, before he stopped walking and let his friend go see Niall alone. Louis glanced at him before he continued walking to the main stage. When he got there, Niall was already sitting and checking his injury.

"You alright, Ni?" Louis asked, standing in front of him.

"I've been better." Niall scowled, rubbing his knee. The brunet frowned worriedly at that, then he took a closer look at his knee. It was bleeding, but Niall already wiped most of the blood with a tissue so it doesn't look that bad. But Louis could tell by Niall's face, that it was getting really painful for him.

"What happened?" He asked the blonde. Niall sighed and he started to rub his knee slower. "It was hit by an iPhone. And, it was really hard." he said, wincing from the pain.

"Do you want to sit down? Or take a break?" Louis suggested to his friend.

"I'm already doing that, Lou." Niall pointed out, chuckling. Louis blinked, he didn't understand it at first. But when Niall gestured that he was already sitting down and taking a break, Louis couldn't help but laugh.

"No, silly. I meant later, during the song." He corrected, ruffling Niall's hair. The blonde's smile turned to a frown, and he slowly stopped rubbing his knee. He seemed to consider that option, since the pain was getting unbearable by the minute.

But being the stubborn fellow he was, Niall shook his head, declining the offer.

"I can do it. It's only one song." Niall determinedly said. Louis scowled at his decision, but before he could say anything Liam came to them both.

"Hey, Ni. You okay?" He asked, kneeling before him. Niall blinked, confused.

"Liam, what are you doing here?" Niall asked the older boy, ignoring his question.

"Yeah, I thought you were talking with the fans." Louis added. He looked over to the front stage and saw Harry talking instead.

"Haz got it covered for me." Liam said to Louis. Then, he turned back to Niall and gave him a worried frown. "But seriously Niall, how are you?"

Niall bit his lip and began to rub his knee again. "Not really." He explained in just two words.

Liam noticed Niall's hand rubbing his injured knee, so his attention switched to that. "What happened?"

"A fan hit him with a phone." Louis explained, crossing his arms. He was clearly seething at the fact that the fans threw something hard at Niall's injured knee.

Liam gently put his hand on Niall's knee, and glanced up at the boy to see his reaction. Niall winced when his hand touched the spot where he was hit, so Liam pulled his hand back.

"Can you still do the concert, Ni?" Liam asked the Irish singer. He was clearly still in pain, but Niall gave him a nod and began to stand up.

"Whoa, easy there Niall." Louis moved to his friend's right and helped him stand up slowly. Liam did the same and helped him from Niall's left side.

"Come on, guys. The sooner this concert ends, the better." Niall said, giving them both a half smile.

The two boys shared a look before nodding reluctantly. "Alright, Ni. I'll tell Harry to shut up." Liam said, ruffling his friend's bleached blonde hair before going back to signal Harry to stop talking.

"Are you sure?" Louis stepped away from Niall and began to walk in front of him. Niall rolled his eyes at the brunet's worry and gave him a nod for the umpteenth time that day.

"Yes, Lou. It's only one song, I can do it."

Louis still looked unsure, as always. But he didn't push the subject and just patted him on the shoulder. "If you need anything, tell us okay?"

Niall nodded, and he gestured for the brunet to go join the lads. Louis understood, so he gave him a reassuring smile before walking ahead of him to the front stage.
