Fullmetal Alchemist

After losing his right arm and left leg, Winry took on the role of Edward's personal automail mechanic, building him sophisticated new limbs when she was eleven years old. Since then, Winry has served as Ed's constant well of support, both mechanically and emotionally, though they still find themselves arguing frequently due to their stubborn and hot-headed personalities. However, this affectionate hostility appears to be masking a deeper relationship. Although Edward has not outwardly admitted any romantic feelings toward Winry, he is rather overprotective of her and becomes unnaturally flustered at the mere suggestion of an amatory relationship between them. Winry, for her part, has admitted to herself that she had been falling for him all along. Edward also says in various occasions that he hates seeing Winry crying and he blames himself whenever it happens, which is something acknowledged by Winry, as she promises him that she will smile for his sake.
