My luck is being drained away!

Um... my little sister asked me to pull some gacha for her, so I used 10 tickets and got a rainbow-colored guaranteed animation, pulling two characters. ...And then a shocking truth was revealed... Yesterday, while I was napping, she apparently grabbed my finger without permission and tapped it, and then she managed to pull an SSR character from that gacha too... Something like that happened while I was asleep!?!? This is just a complaint that my luck is steadily being drained by my sister.
