While they aren't exact opposites they do have opposing traits. If we could define tsundere as "hard on outside, soft on inside" then yandere would be "soft on outside, psychotic crazy on the inside". In other words yanderes give off that soft, loving vibe on the outside wheras the tsundere is more closed in and quiet.
