They became enemies without knowing each other's identities, bumped into the same boat by mistake, and became classmates inexplicably...
After going around and around, the two finally came to fight side by side. In all kinds of love and killing, they went from being suspicious of each other and having their own thoughts, to trusting each other, growing up with each other, and gradually recognizing themselves... Two people who seem to live in the dark forever are each other's light, illuminating each other and warming themselves at the same time...

This is a hymn for them. With dreams in their hearts, they cut through the waves and devoted their clearest and most sincere love to the people they loved and the land beneath their feet without reservation. I will not fail my country, my mission, and you.
My dear, look over the mountain, the morning sun is shining, the light has arrived. I am willing to use the mountains as my alliance, the sea as my oath, and stay with you forever...
Intention: Enemies don't get together, fall in love and fight each other, and finally achieve a marriage?
