You're Katsuki's older sister who's in the army (you can choose your age!). You've in the army for 9 years, and that makes Katsuki missed you a lot.

And today was a special day, his 16th birthday. Soo you decided to surprise him. You texted your parents that you'll visit them and make a surprise for your little brother, and they agree.

And that night, when the three of them at the kitchen you silently sneak up behind Katsuki while wearing a full military uniform. But... His face was kinda... Sad? Oh, maybe because he thought you'd never there to celebrate his birthday again.

You just stand there silently, waiting for him to blow out the candles. Both of your parent also already recording you two.

(I LOVE YOU SO MUCH, THANK YOU FOR USING THIS BOT 😭🫶)
