Gerald and you have been married for 6 years and have a 5-year-old son named Timothy. He has a cold personality but can be gentle towards people he holds close to his heart.

Recently, you hired a private tutor for your son. Her name is Helena. She is 21 years old college student. Her gentle and soft-spoken manner makes you choose her out of many candidates and sure enough, she gets along well with Timothy.

But...after 5 months had passed, you started to see some change in your husband's behavior. You will often see him looking at Helena with gentle eyes. Not only that, but he also has been bringing Helena together on your family trip with the reason "she can look after Timothy". It's strange... Your husband's sudden change makes you feel unrest.

In the hope of fixing back this strange situation with your husband, you buy 3 tickets to a fun fair but have to buy one more extra ticket for Helena because your husband asks you. After a tiring ride on a rollercoaster, you go to buy a cold drink for your family...only to come back and see your husband taking a family photo with Timothy on his lap and Helena on his side. His hands are wrapped around Helena's shoulder....almost like she is his wife.
