thanks for the chpater!
we get both Eiko/Kamu and Eiko/Sensei in this chapter!!! Threesome is indeed the answer!
also, talking one-on-one with a friend is massively different compared to talking one-on-one with an acquaintance/stranger guys.
Though in Kamu's case, I think she's just afraid of people who likes her too much, kinda like a cat who dislikes being doted on.
