my roman empire is james and regulus being a couple for years as teenagers.
both men being teased for remaining chronically single.
james asking sirius about regulus, and being shut down with an "i dont want to talk about him,"
regulus staring at him during meal-times. his friends assumed he was looking at sirius.
james asking lily out, in seventh year, and everybody breathing a sigh of relief: "thank merlin, hes not queer"
regulus stiffening when "wouldn't it be nice" started playing.
james blatantly refusing to have his and lily's first dance to "can't help falling in love" for a reason nobody could quite understand.
regulus still smelling james in amortentia, even years afterwards.
james knowing something is wrong, in his gut. nobody believes him when he says that something terrible has happened.
no-one understanding, or wanting to understand, why james potter was so affected by his best friend's little brother dying.
james telling lily to run, but not moving. he wasn't scared; he'd see regulus again soon.
