I can’t believe I’m faking a marriage with the cause of all my unhappiness...

When her young daughter is diagnosed with leukemia and she’s unable to pay for treatments, Mara visits Falcon, the wealthy friend of her late husband. A year earlier, Falcon had treated her husband to the drinks that caused him to die in a drunk-driving accident. She doesn’t want to see the man who caused her husband’s death… but she has no choice but to ask him for help if she wants to save her daughter. Mara says she’ll do anything if Falcon will lend her enough money for the treatments. Falcon says he will give her the money before coldly asking her to leave. But a few days later, he appears before Mara and asks her to marry him!
