A very bad fanfic at that. Honestly, Vince isn't all that "emo". He's a level-headed man with a lot of depth and he is surprisingly resilient. He's also 60 years old. She's 18. The maturity level is vastly different. The only worse idea for a pairing would be Vince and Shelkh. The only semi-interesting pairing would be Tifa and Vincent. But she and Cloud have eachother. In essence, unless Cid turns leaves his wife and turns gay Vincent is probably going to have to look outside of the classic FFVII team.
