Eijirou was a shy and quiet kid. Kind of ironic for someone who was obsessed with manliness and anything related to the sort. Though he didn't have many friends in middle school, he still tried to seem and act like he was tough, hoping to maybe impress some of the other kids. He'd been eating lunch and minding his business like always, when he overheard some girl squealing about how she met her soulmate. He listened to her explain how 'cute' their meeting was and how beautiful the world seemed.

Hearing the chatter about soulmates made the boy stare at the sandwich he had been eating. He was sure that he had a soulmate, but doubted he did at times. He was moving soon and kind of hated the idea. Ending your third year of middle school somewhere you didn't know was scary. He sighed and pulled out his phone.

RiotFanEi- so I have a problem
Denki117- and that is? :0
King_Suki- !?
RiotFanEi- I'm moving and idk if I'll know anyone
Hanta_Montana- Might be fun dude

King_Suki- meeting you weirdos might be the death of me
Denki117- aw shoosh you know you love us milord
King_Suki- As if- I only talk to you guys cuz im bored

Eijirou just laughed at his group chat. He found these guys on a forum for prospective UA candidates. He had grown particularly close to King_Suki. He would message him in private a lot as a matter of fact. They'd talk about all kinds of things, anything and everything really. Soon school let out and Kurusu had to leave his house and move in to the next town over. Tomorrow he would start his new school and god was he nervous. 

RiotFanEi- Suki do you think we'll actually meet for real?
King_Suki- well yeah idiot. We're both getting into UA right?
RiotFanEi- what if I'm not good enough? My quirk sucks.
King_Suki- ah geez Ei. It does not. For the 1000th time youre gonna be fine
RiotFanEi- if you say so..
RiotFanEi- Hey can I call you?
RiotFanEi- you don't have to tho!
King_Suki- Calm down Ei- sure whatever I don't mind

Katsuki covered his face and was smiling like an idiot. He felt weird thinking about Ei. Talking on the phone and getting to hear him wasn't something he thought he'd do. A minute later the phone rang. He immediately picked it up and answered.

"Hello Ei?" Akiyama said curiously. "H- hi Suki.. I don't know why I wanted to call I was just curious." "Curious of what? How I sound?" The blonde said leaning back in his bed. "Yeah heh.. That's not weird right?" The dark haired teen said kicking his feet off the bed. "Nope- not really, so you're going to a new school tomorrow huh?" Eijirou sighed. "Yeah I am. Do you have any advice?" Katsuki thought for a second. "Just be yourself.. If someone doesn't like you, tell them that your friend Katsuki will beat them up." He smirked. So his real name is Katsuki. "Katsuki Huh? I like it." The dark haired boy smiled. "Oh shut up Ei, Look you'll be fine. Call me or text me tomorrow if things start sucking. Okay?" Katsuki said genuinely.

"I promise I will." Eijirou said smiling a little at his wall as the two continued to talk about random things till they were both ready to go to sleep.
