Oh it was there ahahahaha thanks
lol it's okay I missed it too
Why didn't Suguro-san gave Kotaro-kun a bite mark on the nape? I'm pretty new to an omegaverse-themed manga but I'm pretty sure that a bite-mark on the nape from a fated partner to an omega is a sign that that omega is taken and cannot respond or be in heat if it's not with the their fated partner. Plus that signifies a strong bond between 2 people not of the same blood but loves each halves, right?
