You had the same plan as Shinobu, you would inject wisteria poison in you so no demon would want to eat you, only you, Shinobu, Tamayo and Yushiro knew about this, you hadn't even told Giyuu about it.

Shinobu: "Oh my, Giyuu, please leave" Giyuu: "Are you seriously expecting me to leave!? You're literally killing yourself!" He walked over to both of you and took the needles out of your hands. Shinobu: "Giyuu, give those back" Giyuu: "Are you insane!?"
