I tried something like a head-cannon and also I want to share the websites for you!
The popular website I use is Hikaku, a Japanese website. I got my headcanon and estimated Saki's height based on this picture of Sebastian, Saki, and Ominis going to the Scriptorium together.
At first, I had no idea how tall Sebastian was. I guessed he was around 180 c.m, or maybe even taller. But I'm not very good with numbers, so I just rounded it to 180 c.m (180 c.m. = 5' 11").
For anyone who wants to see how your MC compare to each other look likes, you can check out this link I've left : hikaku sitatter - height comparison chart
I found this shared on Facebook. At first, I was a bit confused, but after using it, I felt like I understood the perspectives of each character, even the MC, and how she really sees Sebastian, and how Sebastian sees the female MC as well lol
As far as I remember, this website allows you to move the character you're simulating as close or farther away as you like. However, I want to mention that you'll need to use a translation this website if you can't read Japanese (like me) I'll leave the link here

Ah, I found this website from shared by my mutuals on Facebook. It's the same converting your characters' heights into hand sizes for those who want to draw MCs and their favorite characters holding hands, or simply drawing hands of similar sizes.
But actually, seeing the size of Saki and Sebastian's hands and their height makes me really want to draw them in a size-diff OMGGG😭😭
Here's a link for those who want to use their MC height to measure hand size : ✋手の大きさ比較ツール
I believe many of you have seen this website on TikTok and are somewhat familiar with it, but some may not know the website. However, I've found it for you, along with tutorials on how to use it in case you can't make perfume like the picture I've left
But first, I'd like to talk about the perfumes I designed for Saki and Sebastian and what they smell like.
Of course, starting with Sebastian, since I'd never used men's perfume before, so much so as just smelling it, I found it very hard to create a perfume that Sebastian would use. So then, I tried to select elements that were plausible, such as the sandalwood scent, which many people agree is a deep, familiar scent in men's perfumes. I put it them that, and for the rest, I just used my imagination lol
Next, for Saki's perfume, I can honestly say it was very easy to design this. I imagined and tried to base it on memories of shopping with friends, and I always like going to women's stores. So I tried to think of a scent with prominent floral and fruity notes, similar to a Bath & Body Works perfume. Plus, Saki is relate about cherry and peony, so I included those, followed by green tea flower and cherry blossom to give it a sweet, soft feel, just like her.

Here's how to access the website and make the form look like the image I left. Follow the link and follow the instructions in the images : Perfumes and Colognes Magazine, Perfume Reviews and Online Community—Fragrantica.com
Imagine: Years after Jonathan and Loki broke up, they get along as friends. Loki's finally accepted the fact that Sebastian is gone forever and there'll probably never be anything romantic with Jonathan but anyone who knows Loki well enough (aka the kids) can see that s/he's fallen for Jonathan. So Frigga convinces the others to plot a scheme with her to get their parents alone in a romantic setting after one of their wedding receptions (maybe Max and Tait's wedding or Sera's wedding). So, they get the two to stay after and help 'clean up' but then the lights dim and Frigga and either Tait or Lucifer sing this song while the other two pressure their parents into dancing with each other.
