So, I (17F) might be the villain here, but I’m honestly still torn.

At my high school, we have this tradition called Senior Assassin, where seniors play a game involving water guns to “eliminate” each other. It’s supposed to be fun, but sometimes it goes too far.

My (now ex) boyfriend (18M) decided to eliminate me in the most humiliating way possible. During lunch, in front of everyone, he ambushed me with a water gun, soaking me and my food. Everyone laughed. I was mortified. He knew I hate public embarrassment and had promised to keep it low-key.

I was furious.

Knowing he was obsessed with his hair and used this expensive shampoo, I added some hair removal cream to the bottle when I was at his house. I didn’t think it would do much—just mess with his hair a bit.

Well, he came to school with patchy, thinning hair and ended up buzzing it all off. He was livid. During second period, he confronted me in the hallway, yelled at me in front of everyone, and broke up with me on the spot.

Now, people are calling me crazy, saying I took it too far. But he humiliated me first. I just wanted to get back at him.

So… AITA?
