Is Tiera starting to fall for Shin? No love triangles, please...
Then again, even the Lindotte twins seem to have a thing for him too, so even if I say I don't want this to turn into a harem, it already has the necessary number of potential love interests for it to be one. I wouldn't blame Celica for feeling jealous by the way they entered the guild building. Wonder how Schnee would've reacted were she there to see that.
