I have some good reasons so I thought I'd make an article about it :) This article is not for the purpose of changing people's minds. This article also contains why I stopped shipping Gwuncan. I don't hate ou dislike Gwuncan, they just aren't my cup of thé right now.
1. From Gwen's précédant relationship with Trent, even though she won't admit it, Gwen wants a boyfriend who will write poésie for her, buy her flowers, and sing songs to her. She wouldn't dare say that to Duncan though. Since he's like the exact opposite. Not that he can't be romantic at times.
