what ISN'T it about seungchan…… no but to answer honestly, i find it so fascinating that they're either nearly identical OR they're basically mirrors of each other. they're both dedicated and stubborn and they both have difficulty expressing themselves directly… chan carries guilt with him on the daily, seungmin tries his best to lighten that kind of load as he goes along… their mutual respect is so important to me. also their voices are gorgeous together, that helps too
