I don't blame you for shipping them, they're very cute and they both bring out the best in one another and unlike other pairings it feels like they're in actual legitimate love, not 'I like you because your cute' love or 'I like you because you do this and this for me' love, it's more 'I love you because you're you and I wouldn't trade that for anything' love. And if you take their confession in Blanc's game out of context of the silly game it was in, the two really do care for each other a lot, and if you ignore Blanc's interruption the confession feels genuine and so does the love they feel for each other.

That's just my opinion though.
