Blue_psycho312's manga / #Jellyfish(1)

I'm so invested with this story line. The characters are somewhat likable and it's quite juicy I'm just wondering if Mitsuki is a magical being (clearly) and in immortal. He goes around, granting people their need for love then disappears when it is granted, only to be "reborn" to help someone else without the memories of his prior missions? This is quite intruiging HMM
