But only I think Fabia and Shun make a great couple?

There's quite a lot of the fandom who would agree with you, actually.

I really don't see the chemistry though? Fabia only fought him to gauge how much she could rely on him, and trust him. Hell, Fabia reportedly has a crush on Dan (unsurprisingly...)

I don't recall anytime, other than Shun believing her (when he was already suspicious of Ren), that could be taken in a ship way? I know there's ships built on far less interaction, but believing someone isn't enough for me to bind them together with a red thread.

I think Shun got shipped with a lot of people, originally, as a fantasy fulfilment thing; Shun was the most popular character (that's up for debate now, though), and people tended to ship him with anything that looked Y/N enough. Alice and Fabia are the very Y/N characters of the series(the hidden evil-damsel type Y/N, and the warrior princess type Y/N, respectively), so it's unsurprising to me that they were the main f/m ships that involved Shun.

(That being said, I don't ship Shunalice either. It was very one sided in s1, and Alice doesn't show up much afterwards.)
