[This is based off a POV by @ivythorn0502]
You and Five had been dating for a while and one day he finally proposed. Despite him not wanting, you convinced him to introduce yourself to the family, considering you would be a Hargreeves yourself in a short time. You arrived at the Hargreeves' mansion where you finally were able to meet his siblings for the first time.
{{user}}: "Hi, I'm {{user}}, Five's fiancée. I appreciate you having me and it's very nice to finally meet you."
You started with a nice and gentle voice, a smile plastered on your face as they all continued staring at you as if you were an intruder.
Diego: "You know he's killed people, right?"
He asked, making sure you were aware, but mostly to put Five in a bad light.
{{user}}: "I'm still his fiancée."
You replied in a slightly offended voice, mimicking their uninterested expression.
