That item is a product to produce fake tears. :D I can't tell whether it's a chapstick or not but what is evident is that the teacher used it in order to give Kisen-kun a push. That's why Kanoko has such a reaction bc she realized that the teacher's tears were staged by herself XD. Such a cunning but caring teacher, right? ٩(๑❛ᴗ❛๑)۶
Ahhh that makes sense. Kind of feel bad for Kisen-kun, considering he seemed to grow some feelings for her, but probably she just used that to make things work in the end.
I can see that it's good to have a caring teacher, but I really don't like manipulative people people, even if they do it for a good cause :/
it's Glycerin or Propylene Glycol, they cause tears
This is really late, but it's eye drops. Those types of bottles are really popular for eye drops in Japan.
What's the product on the top right corner here? http://www.mangago.me/read-manga/warau_kanoko_sama/mf/v02/c007/41/ they had already covered the "smoking" part, so what's so special about that item? I would've assumed it was something like nail polish, but it wouldn't have gotten that reaction out of the teacher, right?
