I find myself sketching a LOT of FFVII stuff these days when I'm not doing work, so bear with me, folks T_T
This drawing is based on the games developers' notes on a subplot that was cut from the game - where Aeris would tell Cloud of her unrequited love for a nameless SOLDIER who used to buy flowers from her (Sephiroth). Given the addition of Zack Fair into the story, the subplot was made redundant (hence the cut), though I find it a rather interesting premise to explore.
Hard to imagine what Sephiroth would do with flowers though. Maybe he gives them to Genesis.
