You're insecure

                                    

                                          
Ashton: 
                          
You were shorter than your boyfriend, Ashton, by about a head. Whenever you stand next to him, he towers over you like a giant, and you can't help but feel insecure about being so short, especially when the fans make fun of your height. You sighed as you looked up at him, and he glanced at you when you did. "What's wrong?" He asked, as he stopped walking. You stopped walking too and turned to face him, "I'm too short for you. Why do you keep dating me?" He pouts, and pulled you in for an embrace, before whispering softly in your ear, "I'm with you because I love you. Love means looking past the insecurities, and frankly, I don't care if you're short. I find it cute, I find you cute, Y/N."
                          
Luke: 
                          
You stared at your reflection in the mirror in disgust - you didn't like the fact that you were heavier than normal. To rephrase it, you didn't like the fact that you didn't have a flat stomach, and you didn't like seeing the love handles either. To put it in much simpler words, you're insecure about your body. You were too busy glaring at your stomach to notice Luke come in. He watched as you glared at your stomach for about two minutes, then he finally spoke up. "Why are you looking at 
                          
yourself like that?" You glanced up to look at his reflection and shrugged, "This is how everyone looks at me." He frowns, and wraps his arms around you from behind. "No, I don't look at you like that. I think you're perfect just the way you are, stop looking at yourself like you're worthless, it hurts me to see you look at yourself like this," His words made all the hatred you had towards yourself dissipate completely and you smiled at yourself in the mirror. "I love you so much Lukey, and I'm sorry."
                          
Calum: 
                          
"You're going to a fashion show?" You asked with a frown. Your boyfriend was to attend a fashion show tonight, because Harry, from One Direction, invited him to go with him. "It's only for one night, I'll be back as soon as it finishes," he says, as he pecks your cheek. You weren't bothered by the fact that he's going away for one night, but rather, you were bothered by the fact that he's going to a fashion show. Fashion shows, of course, means seeing attractive and sexy models hitting the runway. You didn't think you were as attractive or as sexy as those models, and you couldn't help but feel insecure about that fact. But you tried to shake those thoughts out of your head and said, "O-okay, have fun. Don't run off with any of those models, ya hear?" He gave you a sad smile as he kissed your cheek, "Don't worry, you'll always be the only one for me. Besides, to me, you're the most beautiful girl to ever walk this Earth. I love you, remember that, Y/N." You nodded and bit your lip, looking up at him, "Umm, you think you can convince Harry to bring me along? You know, for um, chaperoning?" He chuckled and shook his head at you with a grin.
                          
Michael:
                          
"Can we please get a picture?" Michael looked at you, asking for approval and you just nodded. You looked down sadly as you watched three gorgeous girls hug his waist and pull him in to take a picture. You loved the fans so much, but you couldn't help but feel insecure about the fact that each and every fan he meets is 
                          
prettier than you. You're scared of the possibility of him leaving you for one of the prettier fans, and that made your throat dry up. Once he finished taking pictures, he approached you and slipped his fingers in yours, saying, "You're so much prettier than all of them, Y/N. You're the prettiest girl I've ever laid my eyes on, and I'll never ever leave you for any one of them. You're the one I love," before he leans in to kiss your forehead.
