He falls in love with his own reflection and perishes, not being able to leave the beauty of his own reflection. Who is this?

Narcissus in Greek mythology fell in love with his own reflection in a pool of water and was unable to leave, eventually wasting away and dying. The narcissus flower is said to have sprung from where he died. Echo was a nymph who could only repeat others' words, Teiresias was a blind prophet, and Nemesis was the goddess of retribution who punished Narcissus.
