The lunch bell rang as I stretched my arms over my head through a yawn.

"Good lesson class, remember to finish your homework before next lesson." The teacher lazily commented as they tidied up their desk.

"Finally, I was so fuckin' bored listening to the teacher ramble on." Mammon commented as he stood up, stuffing his notes in his bag.

Satan rolled his eyes and left first with Levi. I stood up and closed my eyes while leaning to the left to stretch my back some more. When I opened them, I noticed Beel staring at me. He smiled softly as we made eye-contact, making me blush slightly.

"Are you two ready to go?" Belphie asked through a yawn. 

Beel and I nodded as we began to wonder out the classroom. The brothers chatted amongst themselves as I checked my DDD. There were a few notifications from Devilgram but nothing important so I put my phone away and moved my arms across my chest to stretch out my shoulders.

"You okay Y/n? Is your back sore?" Beel asked as I switched to my other shoulder. 

I was touched that he noticed, "A bit, I think I've been slouching too much playing games with Levi lately." 

"And when we do homework together you tend to lean over a lot as well." Belphie added and I nodded.

The conversation drifted away from my sore back to Belphie giving a review of the latest pillow he purchased. We wondered slowly to the lunch room, but left school soon after as we didn't have any more classes that afternoon.

A knock on my bedroom door startled me slightly, but I calmed down when I opened it and saw Beel waiting. 

"Uhm, are you busy?" He asked, and I shook my head, "Wanna come with me to the gym?"

"Sure! Just let me get changed and I'll meet you at the front door!" I said and he smiled, nodding.

I quickly changed into a simple sports bra and shorts, and stopped by the kitchen to fill up a bottle of water. I knew I wasn't going to be able to keep up with Beel at the gym, but I assumed he just wanted some company, which I was happy to provide. Beel was waiting next to the front door in a loose tank top and shorts looking at something on his DDD. I blushed slightly at the realisation that I was going to be at the gym with Beel, where he was going to be working out, and would likely look even more attractive then usual.

Beel looked up and grinned, "Ready to go?"

"Yup!" I said, doing my best to ignore my thoughts.

The gym was only a short walk from the house, and it was mostly empty due to it being dinner time for most people. Beel and I both did a quick warm-up on the treadmills, and began our separate work outs. He focused on weights while I spent most of my time on the cross-trainer and bike. 

I really did my best not to stare at Beel, but something about the way he effortlessly picked up such heavy weights made my knees weak. Our eyes met a few times, but each time Beel would just smile or wave at me as he toweled off.

"Done for today?" He asked as I got off the bike.

"Mhm."

"Alright, let's stretch before we head back." He said and I followed him to a separate room with soft mats.

It was just us now, and I felt a bit nervous for some reason. I sat on the floor and put my legs out in front of me, doing my own routine while I watched Beel's strong arms stretch in front of his torso. He noticed me staring yet again, and I looked away, face red from more than my workout.

"Y/n?" I turned to face Beel as he said my name, "Does your back feel better after a workout?

"Hmm? Y'know, know that you mention it, it does feel a bit better," I said and moved around easily. 

Beel smiled, "I thought it would. I know a few exercises that should help strengthen your back muscles and core, want me to show you next time?"

"Sounds good! In return, would you like me to make burgers for dinner tomorrow?" I said and his eyes sparkled with obvious excitement as he nodded. 

"Ah, I'm going to take a photo for Devilgram, would you be in it?" He asked as he grabbed his phone from next to his drink bottle.

I nodded and walked over to him as he held his phone up for a selfie. As I leaned into frame, I stumbled slightly back and feel into Beel. I managed to play it off as how I was posing for the photo and smiled at the camera. I could feel Beel's heartbeat against my back, from how close we were which made me blush slightly. We smiled at the camera and I leaned my head close to Beel.

"Is this alright to post?" He asked and showed me the photo. It was a nice image of us, we both looked quiet good, especially Beel.

"Sure!"
