You will finish off with the after part of the Haftarah blessing after the Haftarah portion is recited.
While the V’ahavta and your Torah Portion have the same chants, the Haftarah chants are different. The chant is based on trope, a musical notation system. The Haftarah has its own specific trope separate from the Torah trope which is why the melodies will sound new and different when learning the Haftarah blessing.
