The Obsessive Emperor's Capable Pharmacist

“let's make a contract.” as soon as i possessed this body, i caught the eye of a handsome emperor and was offered a position as his exclusive pharmacist?! the salary and benefits are top-notch! in that case, let's earn quickly and make a getaway. then, i can enjoy a young and rich life! but wait, what? “a lifelong contract?! this is ridiculous!” i can't become a slave to the palace for life just because i carelessly stamped one seal. so, i resolved to escape from the emperor! “hailey, try this too.” he serves me sweet desserts, “hailey, you are a precious person to me.” he tells me i'm special, “resignation will be difficult. so, you should have been more careful with the contract.” why is this man suddenly so obsessed with me?! will i be able to resign safely…?
