"It's not FAIR!" You screamed, grabbing a vase and smashing it into the ground. You looked around, most of your apartment was smashed to pieces. Glass was everywhere, picture frames scattered on the floor, piles of what looked like love notes all over the counter and floor. Everything was a disaster, most of the stuff in your apartment was destroyed aside from straight up turning the furniture over.

Why was your place a mess? Well, your lovely ex-boyfriend, Katsuki Bakugou, decided to cheat on you that night. Why? Who fucking knows, who fucking cares. All you knew was it was with that slut, Mina. She'd been pining after your boyfriend for months, and I guess she got her fucking wish.

You grabbed a photo of the two of you, looking at how happy you were. 

What a fool to believe it was all sunshine and rainbows, huh?

You grabbed a lighter and burned it, as well as every other photo of the two of you that you had. You were cursing, screaming, crying, the works. You had been nothing short of insane that night, and for good reason.

"Shit- Baby, I promise- It's- It's not like that! Shit. Baby please, come here, you know I only love you!" He yelled as you ran out the door.

Disgusting.

You looked around your apartment again, before deciding that you had- no, needed to get out of the house. You grabbed your coat, slipped on your sandals, and practically punched the door open to get out. You don't know if there was anyone around, you didn't care. You were going back to where it started, to erase the very first part of it all. 

That damn tree.

You got to the park, it was cold and windy, but your adrenaline was pumping so hard that you couldn't feel a damn thing.  You walked further and further down the road, before stopping at a very specific cherry blossom tree. You looked around it for a moment, before you found it. The small carving you made all those months ago. It would've been a year next week...

You looked at the carving, your and his initials carved into the tree with a little heart around it. It made you sick, knowing that he threw all of that time away for a bitch who only got with your boyfriend to spite you.

Before you knew what you were doing, you just started wailing on the tree, right on that spot. You wanted to destroy that heart, hell- you wanted to destroy the whole damn tree if you could, but for now, destroying this little heart was good enough. You continued wailing on it, punch after punch after punch. You couldn't even feel any pain at that point.

You had no idea how long you'd been there, just beating the shit out of this tree. Your knuckles were bleeding profusely at this point, but the heart was barely recognizable, and the letters were gone, so you didn't care, you just kept going. You didn't stop until you felt a hand on your arm, forcefully pulling you away from the tree. You thought it was Bakubitch at first, and you raised your arm to start hitting him too, when a familiar, much kinder voice, spoke up in a slight panic.
