(So...I didn't know it was our other hard boi's birthday, so I'll just continue off the last one to start this one!)

Tetsutetsu: Hey! I'm also throwing a party, maybe after we're done with the cake, you guys can come over to my place!

Kay: It's your birthday too?! Why didn't you tell me?! I would've done a combined birthday!!

Tetsutetsu: I didn't want to trouble you...

Kirishima: We're just about done here, let's go and head to your place.

Tetsutetsu: Okay!

*All the students head to Tetsutetsu's*

Aizawa: I'll clean up. *starts cleaning*

*they get to Tetsutetsu's*

Tetsutetsu: Okay! It's not much, but it's a party! 

*Had a really nice cake, great music, and awesome decorations*

Kay: You did all of this...by yourself?

Tetsutetsu: I had some help from Kendo. And Frost!

Frost: *already there, smiles* Happy birthday, bud!

Tetsutetsu: Enjoy the party!

*everyone hangs out and has fun*

Kay: Wait...I need to get you a present!

Tetsutetsu: Nah, I have enough things.

Kay: But I must! I gotta show how much I care about your birthday!

Tetsutetsu: *pats her head* Just showing up is enough. Besides, you planned a whole party in under 24 hours, you don't need to prove anything to me! You made my bro's birthday great! And you're a great person just by being yourself. *smiles*

Kay: *smiles gently* Okay then.

Monoma: You invited class 1-A? Why do you want to stoop to their level?

Koy: Bro, could you not be a b*tch for 5 minutes?

Monoma: Pff, you just can't handle how much better our class is! *laughs*

Tetsutetsu: Monoma...just let my friends enjoy the party...

Monoma: Fine, but still, we're beeeteeer! *walks off laughing*

Frost: *follows him around, sipping a cup of soda* Surry guys...

Tetsutetsu: Sorry guys, I don't know what his deal is...

Kay: It's alright! It's not your fault!

Tetsutetsu: I know, but I want you guys to have fun!

Koy: Well, it's more for you than us. *sips some cola*

Tetsutetsu: What?! No way! It may be my birthday, but your guys' happiness is way more important than me!

Kay: Aww... *hugs him* That's so sweet!! T^T

*They party some more, hanging out and just having fun*

Kirishima: I say we had the best birthday!

Tetsutetsu: YEah! 

Kirishima and Tetsutetsu: *fistbump with their quirks*

Jiro: It's kinda scary how much they're alike...

Mina: I know...but kinda cool.

Forst: What are we whispering about?

Jiro and Mina: *jumps a bit, not knowing he was listening*

Tetsutetsu: Guys, I just wanna say thank you for being awesome and coming! I'm glad I have awesome friends like you! Cheers, future heroes!

*Everyone raises their cups and clings them together*

Author-Chan: Happy birthday hard bois!! 

(I hope I didn't forget anyone else's birthday...
