You bet!

They already are a couple!

In that case:

@Tamanna0625 How dare you! Fen-Dra is the best couple in the whole series.

I just asking if it’s okay to type in their wiki pages as boyfriend and girlfriend.

Oh, sorry. Then I agree your point.

Yep. That was clear in Beaks in the Shell and The Last Adventure.

Mama Cabrera: "I have some questions about Fenton's girlfriend."

Mama Cabrera: "So, Huey, tell me what you know about Fenton's new girlfriend."

Huey: Girlfriend? "No... Who says he has a girlfriend?"

Mama Cabrera: "So he does have a girlfriend!"

Mama Cabrera: "Huey here was just telling me about your girlfriend the seamstress."

Mama Cabrera: "So this must be your girlfriend."

Yeah seems about right.
