Actually, girls can give their handmade chocolates to their BFFs too. There is nothing gay about it. But obviously, all-female titles regularly show this for shipping or moe purposes. Now, if on a white day a guy gave handmade chocolate to another guy, then this would already be perceived as something ambiguous. Classic.
@Anrhaa Jashin has never been subtle about her fear of "losing" Medusa as losing the ability to manipulate her financially. They really appreciate each other, but don't wishful thinking looking for some great things here lol.
