Photograph (Hidashi but kinda not)

*THIS IS AN AU WHERE THEY ARE NOT RELATED*
Hiro is has lived in his Aunt Cass's café ever since he can remember. It's always just been him and her. However, when Hiro was sixteen, a boy named Tadashi moved in.
A lot changed. Hiro got a girlfriend, Tadashi got into college, but they stayed close, like brothers.
But a rather... awkward situation causes uncertainty and fear to come into the scene, and everything Hiro thinks he knows spirals out of control.
