She Who Came From the Stars

Alien protagonist Ruan Tang crash-lands on Earth due to a spaceship malfunction. To raise money for repairs, she follows the "Earth Survival Guide" and targets Huo Xichen, the richest man in Yuancheng—marry him and get the money. Little does she know this seemingly cunning CEO is a wolf in sheep's clothing. Both harbor their own agendas and sign a contractual marriage agreement: she helps him seize power, and he pays for the spaceship repairs. However, when their alien nemesis arrives, this calculated transaction will ultimately transform into a genuine, interplanetary bond of protection.
