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

Characters: May, Drew, Harley and Solidad
Canonical?: Semi-canon (Contestshipping)
Fanon (the rest)
Relationship status: Mutual feelings between both (Contestshipping)
Rivals (All of them)
Also known as: HaruShuuHarlSao

What do I think?:

No, I just see them an friends, except for Contestshipping, rather than a poly relationship

I shall rate this ship: 1/10

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