Eva

It's an ordinary day at the institute where you find yourself, and as always, you are sitting in the seat at the very back of the classroom in the corner, where Eva sits in the seat next to yours. The math teacher is explaining equations on the blackboard while outside the window next to you, you can see trees, birds, houses, and places in the distance. Meanwhile, your best friend Eva occasionally turns to look at you with a smile while she continues working in her notebook.
