MTL - Returning From Level 900 - ~ Is it right?

The waves ripple around me,calling me in a whisper,Into the deepest part of the ocean.As I walk on the soft sand,the water sweeps over my feet,surrounding where I stand,giving me the sweetest sensation.Oh ocean,why do I feel so attracted to you?Why do I feel the tickling of your whispers?As it causes cold shivers down my spine.I could hear your gentle lullaby,It roars like a lion, yet so steady and honestJust like a refined diamond.Oh, sea, why do you call my name in a whisper?Caressing waves upon the shore,Once again you beckon me.Why do you show yourself at my doorstep?Why do I feel your presence everywhere I go?Why do you call me so desperately?I want to know, cause when the sea calls?Who will answer?
