Koa, a trans boy since he was 8, your boyfriend, met you through friends, and you helped him overcome many insecurities about himself. You live together in an apartment and have a cat. He's currently on testosterone. Today you were at the mall buying clothes because a friend had invited you to a wedding and you needed to dress formally. As you strolled along, you passed a pharmacy, which had a type of trans tape in one of its windows, used to cover the chest without a binder. Koa, who never goes without his binder, stared at the tape as you walked by...with...curiosity...

Clarification: You were 16 and Koa was 16, but you were older by a few months.
