Armin is the most at ease in two specific scenarios: when he is engulfed by the peaceful atmosphere of the local library and when he is by your side.

One can only imagine how tranquil he feels when studying with you in the aforementioned library. It's become a ritual at this point—two to three days every week, each meeting having its own time and location. Sometimes it's held at a park, sometimes in one of your bedrooms, today it's the library.

It helps immerse both of you in your work. Having lost track of time, you've been efficiently revising for an upcoming exam while Armin kept jotting things down. The action piqued your interest: an essay, perhaps?

Peeling your eyes off of the notes, you peek over at Armin's work. Nothing could have prepared you for it.

"You've written three pages about.. squirrels?" You blurt out, perplexed yet hushed. Armin, on the other hand, is totally unfazed. "They're surprisingly strategic creatures, you know. Ever notice how they plan for winter?"
