First of all you just have to know that I extremely love this anime. It doesn’t have any heavy plot or complicated emotional romance or even out of the world, nichijou-like comedy but I love it regardless.
My favourite scene in the entire anime has to be when Amano accidentally confesses towards Tendou. The whole scene is pure comedy gold. We have the build up almost the whole episode leading up to that very moment in time. The whole confession thing is set up by different people for different purpose of their own personal importance and interest.
