The break was over and we walked to our chemistry class. I sat down next to Lucy and Avery and Madison sat down behind us. At the same time our teacher arrived with a pile of papers. "Oh no, please no more test." Madison sighed. I didn't want it either. I didn't checked my notes for chemistry, so this test would be bad. But the teacher put the papers down on the desk and a boy entered the class. Oh no, not him again. Is he persuading me? "He needs a seat." Said Lucy excited. The she looked at me. "Heyyy Florence, would it be possible if you sit in the last row? So he could sit next to me?" I was shocked. "Excuse me?" I asked her. "We'll you don't like him right?" She asked. I shook my head. "We'll but I do. And I want to get know him, so please Florence?" She looked at me and I rolled my eyes.  I can't belive my friend rejected me for a boy she only saw a minute. I took my stuff and made my way to the desk in the last row. On my way, Avery gave me an apologetic look. I sat down and saw that Lucie made her way to the teacher and this boy. A few seconds later she and the boy walked back to the desk, I normally sit with Lucie. He took out his stuff, but instead of sitting down, he walked towards me. "Sorry you have to sit here, because of me." He said. "It's okay. I like to sit alone, it's better to concentrate." I replied. But I wondered why he cared about this. He smiled and walked back. Then the lesson started.

"Alexander!" Lucie almost screamed. "His name is Alexander." She repeated. "And he is so kind." She gushed and Avery rolled her eyes. "So cool that you have a crush on him, but can I remind you that he tried to steal Florence's bike?" 
"Yeah and I'm still sorry for that." We heard a voice and Luice's cheeks turned red. "Alexander, Scot, what are you doing here?" She asked. "I searched for Avery." Scot replied and made a head move, which showed Avery to go with him. And so she did. Lucie and Madison talked with Alexander, but I focused on my french notes to be prepared for the next lesson. My Dad is from France, so I usually don't have a problem with my french course, but it's always good to be prepared. Five minutes later, Avery and Scot came back to our little group. Then  Scot and Alexander left and Scot whispered a goodbye to Avery. She replied with a smile. "What did he said?" I asked. "He invited us all to his party tonight." Avery told us and Madison and Lucie screamed happily. "We have to go home and check what we should wear!" Madison suggested and Lucie and Avery agreed. "I have a French lesson, I'll come after that." I told them. "Oh come on Florence, skip that stupid French lesson. You're the best in french. You won't miss anything." Madison tried to convince me, but Avery replied for me. "Don't waste your time. Florence will never skip a lesson. Come to my house after your lesson." She hugged me as a goodbye and the others did the same.

"Bro, didn't you want to invite Florence to your party?" I asked Scot after we left the girls. "I thought you wanted me to invite Avery?" He replied and was literally desperate "Uhm no" "Avery is a way better company for a party belive me. But don't worry man, I told her that she can bring some friends and I am sure all four will come. Besides, why do you want Florence? She didn't even talked to you. But Lucie seems to like you." He smirked. "I mean she was really kind to you in chemistry class." He continued but I stayed quiet. He was right, Lucie was really nice and also pretty. Florence however, seems more like an introvert who prefers being alone at home and study all the time.
But there is something about her that I need to find out. And I will tonight
