[WIP] Update lineart page 54, sketch page 55-56 (Patreon)

(please be cautious this is very explicit so open it when you're not in public area!)

This is very challenging than i expected because there's so slight of references about knot scene (visual/graphic... that's very very rareee as far as I've looked for any references?!!!) I'll do my best for the next pages where they'll lock together~ 👀⭐

I'm going to color page 54-55! Please be waiting, thank youu so much for supporting me~! ❤❤
