How is the only thing I could think.

How?

How is he here? My heart was beating like a drum. There's no way he knew I was coming here. I never told him. And.. he wouldn't stalk me, for goodness sakes. He's too cute to do that... WHAT DID I JUST THINK?! I'm crazy! "YN!" Bf/n yelled. "Earth to you! Are you there?" I nodded. "Yeah, yeah." "So let's go. Our classroom and class teacher's names are written outside on a board. We need to go and see." I nodded and Bf/n, Eren, Armin and Mikasa got up and left to see. We pushed through the  crowd and spotted our names. "Bf/n! You're in MY class!" I exclaimed. "YES!!" We hi-fived. "What about you guys?" Bf/n asked. "Well, Eren and Mikasa are in the same class. I'm in a different class."Armin said. "Excuse me!" We heard a girl say. We turned to see her and Armin gasped. Yeah, she was really  pretty, with blue eyes and blonde hair in a ponytail. "If anyone is in section A here, come with me, please." No one reacted, but Armin exclaimed, "I'm in A!" The girl's eyes widened. "Wow, that's great!" She exclaimed. She walked towards Armin and thrust out her hand. "Hello, my name is Christa. Christa Lenz. Nice to meet to you!" "Same here." Armin replied shyly. Someone has hearts in his eyes. Suddenly she blinked, noticing us. "Are these your friends?" She asked. "Yeah." We introduced ourselves and then I said, "Ok, I think we should get to class now." Everyone nodded. "Let me lead the way." Christa said. She took us to a hallway with white walls. "Please tell me your classes so I can take you there." "G." "G.""G." "G." We looked at each other. "Woah!" I exclaimed. "We're all in the same class?" Christa smiled. "That's great, actually. G is the first section in the hall to the right after the bend. There are two wings of University, as you know. Languages and Science. Sections A, B, C, D, E are the Science sections. F, G, H, I, J are the Language sections. So, I'll lead everybody to Section G and then I'll go  with Armin to section A. Is that ok?" "Is that ok? It's perfect!" Armin burst. He blushed a bit after that and Christa smiled. "Great." We kept walking and soon reached the bend. Christa led us to our class's entrance. We said bye and rushed in. I elbowed bf/n and whispered, "Oh, by the way, good news for you. You know Erwin Smith? The Vice Principal? The guy you blushed when you looked at him? He's our class teacher." Bf/n grew red in the face. "No way!" She exclaimed. "Yes. I saw." As if on cue, a tall, blonde man walked in and looked at the entire class with bright blue eyes.

"Good morning, students." "Good morning, Professor." I sneaked at glance at bf/n, who was red in the face and looked as though she might faint. "As you all already know, my name is Erwin Smith. I will be your class teacher as well as your teacher of English for this session. Let me remind you, I am the Vice Principal of this university, so it would be best if you all behave." Or you're in for it, his eyes added. Then that look relaxed and he said, "Now we shall have a few brief introductions." Lots of names popped up but I didn't bother. Again, I looked at bf/n. The poor girl was still red in the face, but she looked composed. Let's hope she doesn't faint, I thought. "And you are--?" Professor Erwin looked at her. Shakily standing up, she managed to look at him. I felt proud of her for being able to face her... uh... I suppose crush in a presentable way. I really doubted I could face Levi the same way. I blushed, thinking of him. Damn it, Y/n! Focus! Do not get distracted! "Bf/n L/n, sir." "Bf/n..." He echoed. Somehow, I felt that there was a bit of softness in his voice as he repeated her name. So, there might be hope for her. Then something seemed to flick in him and he came back to reality. Bf/n sat down and he looked at me. "Your name is--?" "Y/n L/n, sir." I replied. he nodded and I sat down. Te whole thing continued. In the end, he said, "Alright. I know your names well enough. I will be better acquainted with all of you later. Your next lesson is--" He quickly flicked through a few papers--Please don't say-- "French. Your professor will be coming soon. Please be prepared." With that he walked out.

Oh my God.

How can I do this?

How can I face him now, like this?
