I want to headcannon that yuu loves teddy bears but
…i think it’s canon enough XDD
NOW imagine yuu buying lots of teddy bears and snuggling with them while he sleeps.
And Mika gets steadily annoyed by the amount of bears Yuu buys (and is also secretly jealous by his strange obsession over them) that Mika ends up buying a teddy bear suit so that his Yuu-chan can cuddle with him too. LOL
