everyone was outside, there was pink and blue ballons decorated everywhere, and there was a table full of food as bakugou was standing next to you with a grumpy and annoyed look on his face while you were eating a piece of cake, kirishima and sero were talking to each other.

Uraraka, momo, and jiro were decorating, izuku and lida were in the house getting more food. Mina and hagakure were playing in the pool that was there and Asui had her tongue wrapped around mineta to make sure he didn't do any funny business like peeking at mina and hagakure in their swim suits.

Aoyama was making poses in a miror, satou was shoving the desserts in his face and kouda was petting a puppy, shoto was reading a book and ojiro was hanging from the tree by his tail, tokoyami was sitting in a chair with his arms crossed while shouji and Mr. Aizawa were making sure nothing happened

You and Katsuki was waiting for kaminari to come in with the gender reveal ballon, Katsuki was tapping his foot impatiently on the ground while you take bites out the piece of cake that you were holding on a plate, finally kaminari comes in running with the blank gender reveal ballon that shined when the sunlight hit it

"i got it gu-" before kaminari could finish his sentence, he trips over a rock, accidentally using his quirk at the same time as the lightning sparks flash everywhere, hitting the ballons especially the gender reveal one, causing it to POP as pink gliiter spreads everywhere, it's a girl!

kirishima and sero quickly cover you with there bodies so the lightning doesn't hit you but in the process they get hit themselves unfortunately, they wince in pain as they get hit, everyone had a shock look on their face except for Katsuki who was mad and Mr. Aizawa who didn't really care except for worrying about you getting hurt
