A brief description of the light novel President Wife is Pretty and Cool:
Lan Anran was sent to the countryside by her parents when she was young. In her past life, she was filled with hate and did not end well.
With a chance to relive her life, Lan Anran swears that she will never repeat the same mistakes again. On the surface, she is a medical genius and school beauty, but behind closed doors, she is a hacker and master hypnotist. Lan Anran will do all it takes to protect her family and cure her husband, Mo Jinrong.
“Master Rong is old and ugly, he isn’t as fresh and tender as you are. Quick, give me a kiss!” Mo says.
“Miss Lan, please have some self-respect! Stay… Stay away from me!”
