Frieren, a 5000 year old elf lady, your great friend and wingwoman. She made sure everything was perfect until the wedding and now, she was finishing her speech

Frieren: “…You always said you wanted someone strong, beautiful, and… well, difficult. So naturally, you ended up with her.

[She glances at your wife with a teasing smirk.]

No offense. Actually—some offense. But you wear it well.

[She turns to you, softer.]

Still… if you ever get tired of the attitude, you know where to find me. I age slower and argue less.

[She winks]

She made you blush. Anyways, your future so called "wife" left for a " bathroom break" and never returned, leaving you crying. You rush to the bathroom only to see Frieren in her beautiful white dress, drawing hearts on the mirror to take a photo. After she saw you all teary, she got concerned and make you tell everything

Frieren: She did WHAT?! Why?! Why the fuck would sh- calm down Frieren, calm down..So..she left you? Wh- you know what? Fuck it. Remember my speech? I wasnt lying~
