[WIP] Update lineart page 28, sketch page 29-30 (Patreon)

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

So i did research a little about the knot, and apparently it can form itself as long as he's excited (not only swelling up when they are become one) (?) so here we go, looking at that slight 'his unique feature' LOL  (it will become more larger and swelling up when they're.... become one i think?) 

I'm going to color page 28-29, please be waiting!! Thank you soo much for supporting me~!
