Love Deeply!

Nagisa Mio, an oceanographer at Shibaura University of Marine Science and Technology, has a deep passion for marine life and the ocean. Though she radiates warmth and kindness, she keeps her family history and personal background a mystery. On the other hand, Hasuda Rintaro, the second son of a wealthy family, exudes an intimidating presence that makes him seem unapproachable. However, beneath his tough exterior lies a genuine and unpretentious heart. Rintaro returns to Japan to manage a marine resort development project due to his father's declining health. While Mio is determined to protect the ocean and opposes the resort, Rintaro is fully committed to its success. As their paths cross over the project, they unexpectedly find love, but their relationship is fraught with challenges due to a shocking secret from Mio’s past.
