Wow. Just look at that picture. It's beautiful. And so detailed. 

✧✪ ω ✪ ◕ ω ◕✧

The Day of the Sports Festival was more festive than I imagined. I had already took the video that I needed to take, and my teacher, Present Mic told me that it was all ready and set to broadcast live for the people watching online while the people on site take a break and get something to eat or do whatever it is that they need to do. 

To be completely honest, I was dreading having to watch everything from the seats, but so far, it's been really interesting. Izuku slayed the Obstacle Race, and Katsuki managed to get second place for the Calvary Battle. He's probably gonna throw some hissy fit later, but right now, I'm more worried about how loud he's gonna scream when he tells me that Todoroki placed first. 

I sighed. I think I was already starting to get a headache. 

Just kidding. I was happy for all of them. Even the noisy ones. Really...noisy. 

...

Anyway. 

After the Cavalry Battle ended, the Sports Festival let us all off for a Noonday Break. This should be about the time that my video is being broadcasted. Gosh, it's so nerve-wracking. Even though they won't get to see me live, it still makes me skittish that some of the top Pro Heroes would be watching me. 

As I was walking down the hall, I decided that I was going to congratulate the people who've come this far into the Sports Festival. That's when I noticed Katsuki walking down the hall with a scowl on his face. 

I began to follow him, until I realised that he was eavesdropping on a conversation that Todoroki and Izuku were having. 

I was about to walk away from the scene, but unfortunately Katsuki caught sight of me and grabbed my wrist, preventing me from walking any further. 

Forcing me to hear every single word that Todoroki had said. The very words that he only attended for Izuku to hear. Was that okay? Did the Pro-Hero Endeavour really do all that to his own child? 

I don't know why but I felt a little guilty. I heard footsteps getting quieter and quieter, indicating that Todoroki and Izuku must've left. 

And just when the sound of footsteps vanished, Katsuki flicked my forehead. "Ow!" I said, rubbing my forehead. "What was that for?"  "Idiot! You were using your Quirk. They could've seen us." He grumbled. 

"No I wasn't." I protested. He crossed his arms and raised a brow. "Guilt." was all he said. And that was all I needed to hear. "Sorry." I mumbled. 

A few moments passed and he gave me an annoyed glance. "What now?" I asked. "You're still using your Quirk, dumbass." He said. 

I looked down. What was I supposed to do? It's his family business. I don't need to get involved. But I still feel like I could've done something to help. "Look. Icyhot knows damn well that he's got issues. When he needs help, he'll ask for it. And I doubt you'll have to wait that long because he's a wimp. But just know that in the end, it's his stupid familial problems. Not yours. You're just gonna have to deal with that. Got it?"

I nodded. "Good. Now let's go. I'm hungry."  "I've got a Granola Bar if you want it." I offered, taking it from out of my pocket and giving it to him. 

He lightly snatched it from my hand as he continued walking towards the hallway. Just as he took a bite from the Granola Bar, we got stopped by none other than All Might himself. 

"Ah! There you are Young (L/n). I was looking for you." He announced. I blinked. Why was he looking for me? Was there a problem with the video that I needed to know about?
