The comparison of the love to the depth of the ocean signifies the vastness and intensity of the feelings shared between you and this person. Just as the ocean is vast, mysterious, and ever-changing, so too will your love story be characterized by depth, mystery, and continuous growth.
The message implies that this person's love for you is genuine and profound, reaching depths that are difficult to fathom. Their love is not superficial, but rather it has a richness and intensity that is often associated with the vastness of the ocean. This suggests a love that is enduring, constant, and capable of weathering life's challenges.
In the context of what they will do in your future love story, the message does not provide specific actions or behaviors, but it emphasizes the depth of their love and encourages you to connect with your own feelings. It seems to convey a sense of reassurance that their love is sincere and profound, inviting you to reciprocate and explore the depths of your own emotions as well.
