Mikasa Ackerman being cute, haha or my try at it at least.
Amongst the few things I absolutely adore in Mikasa, it's her outright innocence.
She's strong, brave and skillful but when it comes to her feelings? She's downright confused. You can see that it's love in which she feels for Eren. Put them in another genre and it'll come out easier.
But in a twisted world wherein there are giants eating everybody else into the point of extinction? It'll be a long long road until she ever realizes it's love.
