One day You were Just coming back from Grabbing Groceries while storing them in Your Magic Bag of Holding and you were walking down the Street Reading The News on your Phone as you were reading about A Friend of Yours! Tatsumaki AKA the Tornado of Terror!

The News Headline read how about One Punch Man was able to Put Stop to An Alien Threat Named Boro's once again with Help from Tatsumaki who, To be honest Looks like A Child but is actually surprisingly 28! 

She had Recently Been Putting on Weight and it had Surprisingly greatly increased the Potential of her Telekensis/Esper Powers to new Heights as if More weight equals more Power which Makes some Sense as she spends less time on Physical Stuff and more time or Mental exercise!

You walked up the Path to your Mansion and Unlocked the Door to walk inside when You Bumped into some Smol yet Large Figure with Green Hair! Wait... Smol Yet Large with Green Hair? That can Only sound like One Person!

Y/n: "Tatsu?"

It was the Superheroine and like the Tsundere she was she looked at you with A Uninterested look and Frowned!

Tatsumaki: "Look Idiot I showed up Because My Apartment is being Renovated and Nothing else so don't act like I like you or anything Baka!"

Y/n: "Awww, Tsundere~"

You then Began to Pinch her Chubby Cheeks which she Swatted your Hand Away Blushing!

Tatsumaki: "S-Stop it, Baka! Be Grateful That I'm being nice to you! So... You got any Cake?"

Y/n: "Yep, In the Fridge! Should I get them for my Little Tsundere~?"

Tatsumaki: *Blushing* "N-n-no!! I-I can get them Myself!!"

She then used her Telekinesis to Grab A Few slices of A Few Different Cakes and she sat down as she Began eating them while giving you a Side Glare! You then Tried to Poke her cheek again but she slapped your hand away still Blushing!

Tatsumaki: "Baka, You think I want my Cheeks Poked?"

Y/n: "Well to be Honest Tatsu, Your cheeks are so Cute and Chubby like A Little Bunnies, and it's so Cute~!"

Tatsumaki: "S-Shut up! Baka! I'm Not Cute and I'm Not Like A Little Bunny! So Stop it!"

Y/n: "Eh, Fine then... But You're still so cute~"

You then Hugged her from Behind and she Telekenticly lifted A Vase above your head and smashed it on you!

Y/n: "Tatsu, You should know I have dealt with far worse than that. Why don't you tell me the Truth of why You're really here and I'll stop."

Tatsumaki's Face then Glowed A Bright Cherry Tomato Pink and she got really Tsundere Angry!

Tatsumaki: "BAKA! BAKA! BAKA! I AM NOT! I AM NOT A TSUNDERE! I DON'T LIKE YOU! I DID NOT LIE TO YOU! SHUT UP! SHUT UP! SHUT UP! YOU'RE SO STUPID BAKA! I HATE YOU! BAKA! BAKA! BAKA!"

You then started Grabbing her Cheeks and Began stretching them as she tried not to cave into your demands!

Y/n: "Come on Tatsu. Just Admit it. It's not So Fucking Hard."

Tatsumaki: "Okay, I admit it!! I Just wanted to Move in because I really, really like you!! I really am A Fucking Tsundere!! You are such An Idiot so Stop this right now!! Baka!! Baka! Baka!!"

You then Let go and Hug her, wrapping your arms around her Belly as you smiled!

Y/n: "Awww, It's not that Hard now is it? I love you too Tatsu! You're so Damn cute!"

Tatsu: "You're A Goddamn Idiot, Y/n....... But I guess I can say that I love you... JUST DON'T TELL ANYONE BAKA!"

Y/n: "Can do!"
