Kaguya-sama: Love Is War - Season 1 Episode 12

After being forced to bail out on seeing fireworks with her fellow student council members, Kaguya shuts herself up in her dark bedroom. Hayasaka, Kaguya's maid, is worried about her mistress's depressive state. She tries to cheer Kaguya up, and when that doesn't work, introduces a plan to sneak out of the family mansion. Kaguya manages to slip past a pair of vigilant butlers and reaches the venue, but the fireworks display is already over. Kaguya is in tears, since she really wanted to see the fireworks with the others, but then she hears a familiar voice: "Then, I'll show them to you."
