Treasure Secret

The dragon girl Sheng Xingwan accidentally loses half of her magical pearl to an ordinary man, Bo Siyao. This causes her to lose half her powers and, upon contact with water, uncontrollably transform into a dragon. To regain her pearl, she tries every means necessary to get closer to Bo Siyao. It turns out that Bo Siyao is terminally ill and has only a year to live, so he tries to avoid getting close to people to avoid developing attachments. However, his cold heart is gradually thawed by the girl's cheerfulness, and he begins to protect her. When the secret of Sheng Xingwan's true identity is revealed, Bo Siyao faces a difficult choice: use the pearl to prolong his own life, or return it, as without it, the girl will die.
