This is my fancharacter Esk, and the White Tiger team from the third season of the anime Beyblede.
Basic gist; Rei thinks Esk is really cute (in a little-sister sort of way) and she sneezed in a cute little baby way, like baby Simba does in the opening sequence of the Lion King. That was too much for Rei, so he grabbed her saying 'You are so CUTE!' Hence the title. the hissy thing in the bacground is Mariah, a member of the White Tigers who is totally in love with Rei.
