In the first seven episodes, Mo and gigi met and used three songs. The first song is Ode to the Virgin Mary-Rebecca Luke's Stairs to Heaven, but I really want to make appropriate changes, but the tune is still the same, but the rhythm and humming are different (this can be found on Baidu). The second songs "Beauty" and "Beauty" are very noble music. It should be Bach's third song "Ah, Ah, Ah-". I've been looking for it for a long time, and it seems that wireless created it by itself. There is no complete version yet. I intercepted a paragraph by myself with the software (about 1 min 13 seconds).
