Shuangjie~HE~ (With a secondary CP, life will not only have two protagonists)
Don't be cruel, marry first and love later.
The female protagonist Cheng Qianhe × the male protagonist Jiang Shangyan are childhood sweethearts and happy enemies.
Cheng Qianhe has been trained step by step by her family since she was a child. She is a solid, well-behaved, gentle and steady student. However, only Jiang Shangyan, who knows her well, knows how vicious and unstable she is in private.
Jiang Shangyan has gone against the grain of his family since he was a child. He has overturned everything arranged by his family and is idle every day, not doing his job properly. However, only Cheng Qianhe, who knows him well, knows how sly and tolerant he is in private.
Cheng Qianhe, who looks like a good girl and a white rabbit, and Jiang Shangyan, who seems to be a rebellious person, slowly fall in love with each other after their souls penetrate each other's bodies.
Two people who dislike each other lead to a series of contrasting and funny stories.
