Chen Yu was attracted by her strong sense of familiarity and inexplicable attraction, and gradually approached her. However, as the relationship between the two deepens, the truth about the shipwreck three years ago is like an iceberg sinking in the deep sea, slowly rising to the surface and being involved in a dangerous whirlpool.
