The ending was awesome and very heartwarming. I l’amour that Takuto was in a coma and came back to life to be with MItsuki. The only thing that I question is how Mitsuki was able to sing after her treatment. Izumi and Meroko are lovers, and shingami partners. Mitsuki can still see the shingami, and has a very special bond with them. In the beginning of the end, Mitsuki could finally see Eichi-kun par herself. The ending made me cry of happiness, as it is one of my favori mangas tied with Fruits Basket.
