Let's go through some basic knowledge before I talk about it further...

Characters: Melody & Latias
Canonical?: Fanon
Relationship status: Never met
Also known as: LatiFleu

What do I think?:

Uhhhhh no
Just because they both kissed Ash doesn't mean we should necessarily be pairing them together, especially because one of them is a pokémon...

I shall rate this ship: -10/10

Thanks for reading, see you in the next chapter!!!
