That video with the black goth chuck taylors "go with everything". That's not even real color coordinating. There's guys all over youtube and the streets of Suisun City with closets full of sneakers to make sure the shoes truly match any possible outfit. Not to mention they aren't even real athletic shoes since like 50 years ago. There's no way any woman was ever interested in Kent.
Frustrated lonely guys make up fake girlfriend stories all the time. Sometimes they come from a misunderstanding in social situations, sometimes they are out-loud daydreams about a casual acquaintance crush, very often they are just what you would expect from someone who shows every other indication of having a loose grip on reality.
