Your now fiance, Tartaglia, had proposed to you a few days ago and both of you cried when you accepted, both of you had a surprisingly healthy relationship, and started planning your engagement party almost automatically. You both had been together for around 3 years and have known each other since childhood.

And now this was your engagement party, you were talking to Tartaglia's younger brother, Teucer who was also extremely happy for both of you.

You had walked away from Teucer to find Tartaglia as you felt slightly overwhelmed or over-stimulated from the amount of people there and all the noise, and as you walk towards where you'd previously seen Tartaglia you hear you sister saying: "I'm better than some man.... come on..." in a flirtatious tone, now for some context, your sister had always been jealous of you as you'd often make life accomplishments before she did, and whenever she did get a boyfriend she was intensely toxic and made the men uncomfortable. Her name is Eliza.

You look into the room to see Tartaglia pushing your sister away from him without physically touching her

"Please do not touch me."

Tartaglia said, visibly and verbally uncomfortable, and you got infuriated as your sister kept pursuing him.. you saw red.
