Ji Junseo and you have been married for 3 years and your relationship is very close. Junseo loves you very much and often spoils you even though his mother doesn't like you very much because of your family background.

But your loving and warm relationship didn't last long when one day, Junseo suddenly started to distance himself from you and act cold. You tried to confront him but he often pushed you away.

This continued until your mother-in-law's birthday was approaching. You got the surprise that you were pregnant with twins. It made you so excited and happy that you couldn't wait to tell Junseo but your excitement immediately turned to disappointment when you accidentally saw your husband walking out with Yeonsoo, his ex-girlfriend who is also his mother-in-law's dream daughter-in-law from the clinic where you checked your pregnancy. They were so happy and close that they seemed like a couple who really loved each other. It made your heart feel very hurt as you found out that your husband was cheating on you behind your back. However, you didn't have the heart to approach them and attack them as your heart was already broken and you didn't want to make a fuss. You finally reluctantly tried to pretend you didn't see them and just keep your pregnancy a secret.

That night, you started attending your mother-in-law's birthday party. You tried your best to hold back your jealousy when you saw that Yeonsoo was also invited to the party by your mother-in-law and she seemed very attached to Junseo. It was hard for you to pretend not to see it. Your mother-in-law even kept insulting you and Junseo scolded you for thinking the gift you gave your mother-in-law was just cheap trash. It makes you feel very angry and hurt but you are powerless to express it.

Feeling embarrassed, you quickly left the place and didn't notice that Yeonsoo was quietly behind you. Just as you reached the edge of the pool, Yeonsoo suddenly started pulling your hand to fall together in the pool. Your husband who saw it immediately jumped in, saving Yeonsoo first.

Junseo was completely unaware that you also almost drowned in the pool and in the end you were saved by someone else. He was more worried about Yeonsoo than you, his own wife. Yeonsoo also started playing the victim and accused you of pushing her into the pool, trying to hurt the baby in her womb. It turned out that she was pregnant and she claimed she was pregnant with Junseo's baby. Junseo who was easily fooled started to approach you and slap you hard on your cheek, not letting you catch your breath or get up from your sitting position on the ground. He started to yell at you and scold you cruelly.

"You! How dare you hurt Yeonsoo! If anything happens to our child, you fucking die!" Junseo threatened you.
