(Y/n)'s POV

  "Get away from me, you freak! You've been following me around, acting like we're still together! Don't you get it?! I don't need you anymore, I don't want you anymore! So go away, it's not like I could love someone like you anyway." My now ex-boyfriend shouted at me, voice like venom as he clutched his newly found girlfriend to his side. A million emotions made my quirk activate, and I narrowed my eyes at him as anger fronted.
  "I hope you can be happy, moving on as quickly as you did. Enjoy your new trophy girlfriend." I hissed, walking off with my tentacles unintentionally raised. I walked from the back of the school to my class dorm, going straight to Mr. Aizawa. He was grading papers, glancing at my frustrated body language.
  "Be quick about it." He said, hand pausing mid sentence.
  "Can I go to Ground Beta?" I asked, and he sighed.
  "Keep destruction to a minimum, please." He said tiredly, and I nodded.
  "Thank you, sir." I replied, not wasting any more daylight. The sun had begun to set when I made it, and I took a deep breath as I let my quirk activate again. I grabbed the two lampposts behind me, an angry scream ripping from my throat. I had picked the biggest building to destroy, it would be the only one broken. The lampposts went through the top windows, the bottoms sticking out from the broken bricks and glass. I couldn't tell how much time had passed, all I knew is when I was too exhausted to care... I had zoned back in to reality to see in the light of the in tact lampposts that there wasn't a building anymore. It was a pile of messy rubble, covered in the liquidy substance of my tentacles from the abuse I had put them through. There was also blood and dirt on my hands, probably from pulling rubble towards me to hit.
  "I heard Mr. Aizawa say minimum damage. Just wait till he sees this." A voice said close by. By instinct, my tentacles pointed up in alert, and I out them away as I realized it was Kirishima. He held a small paper bag, a sheepish smile on his face.
  "Hey 'Shima. What're you doing here?" I asked, shaking the dust from my hands.
  "Oh! I noticed you hadn't come back for dinner, so I figured I'd bring you some. Besides, whatever happened... I didn't want you to be alone." He said, gesturing to the bag. The gesture made my heart squeeze, and I shuddered at the familiar vulnerability I had with my ex.
  "Thanks. I'm not hungry, to be honest. I just need to be by myself, but thank you for coming to check on me." I said, turning my gaze from him. Frustration churned in my stomach, my brain stupidly staying angry.
  "(Y/n), you're hurting. I don't know what happened today to get you to this point, and you don't have to tell me. But please, let me help you." He said, and I suddenly wasn't myself. My tentacles pushed me up off the ground, and I couldn't stop the venomous words from leaving my mouth.
  "What? So you can do what he did, and tell me I'm some sort of freak?! Did you come here to put me down for not handling my emotions and having to be violent like an animal?!" I screamed, letting out the whole story. By the time I had screamed it out, I was on the floor, wrapped in my own writhing tentacles. I hugged my arms around my waist, boiling hot tears falling down my face as I sobbed. Kirishima's red hair came into view, and I could feel him moving my tentacles around. Suddenly he was holding me, head on his chest and his arms around me.
  "I've got you, I'm right here. No one's going to hurt you here." He said softly, arms pulling me closer as I threw mine around his neck. My body shook with my hoarse cries and sobs, my tears soaking the material of Kiri's shirt. My bloodied hands gripped at the shirt's softness on his back, taking him in. The faint smell of cologne, the warmth of his hands rubbing my back as my quirk deactivated, his comforting words as his head rested on mine. Finally I could think clearly, and I took a deep breath.
  "Im so sorry, I shouldn't have taken that out on you. I-" I sputtered, pulling back and looking at him.
  "Hey, it's okay... Is that what he really said to you?" He asked, hands sliding down to my lower back. I nodded, sniffling as I wiped my tears away.
  "All in front of his new girlfriend, too." I said, and his eyes widened.
  "Really?!" He said, a smile pulling at his lips in an open mouthed smile as I giggled.
  "Yeah, it was a little stupid. I don't even know why I'm crying if I'm honest. He was an asshole from the beginning." I replied.
  "Well, he obviously aimed at something you're insecure about. But hey, he's gone off without you. You can't be replaced, he'll realize what he's missing soon enough." Kiri said, and I felt my cheeks warm up. We both began to laugh, forehead resting against one another as I hugged him closer.
  "You're a sweetheart, 'Shima. Thank you for coming here, by the way. I was I little deep in my rage to realize I did a number on myself." I said, pulling back in his lap and showing him my hands.
  "Wow! Jeez, don't let me spar with you anytime soon." He joked, and I laughed. He inspected my hands, sighing softly then lifting them to his lips. I blushed as he pressed kisses to the broken skin on my knuckles, making me smile.
  "But seriously, thank you." I said, and he looked into my eyes.
  "Of course, I care for you. I don't want to see you hurting, especially alone. So, let's get you cleaned up and bandaged. Oh, and fed as well because I heard the obvious stomach rumble a minute ago." He said, and I nodded. He helped me up as he stood, delicately holding my hand as we began the trek to the dorms.
  "Okay, I give. I'm starving, tired, and in desperate need of the Bakusquad's famous cuddle puddle."
