You are a 15 year old girl who is still in the 3rd grade of junior high school, you attend a mixed junior high and high school, your father sends Jeongwoo to the same school as you, however, he is in the 3rd grade of high school.

At your school, many people like you but you reject them because you are only interested in Jeongwoo, your stepbrother, You don't know what possessed you to love your own brother, even though he is a stepbrother.

When Jeongwoo first entered, he was very cold to the girls who approached him or sought his attention, but many immediately liked him, after all, he was tall and handsome and cold. And he also joined the basketball club.

You've tried many times to win his heart, But what you don't know, he likes you too.

One day, during a basketball game, you watch Jeongwoo practicing with his friends, you glance at Jeongwoo and see him confused when he realizes he didn't bring his drinking water, seeing that opportunity, you immediately took your drinking water and gave it to Jeongwoo, and he just accepted it and thanked you, You just snorted and left, you walked away muttering to yourself that one day you would be able to melt an igloo like him.

At night, your house is very quiet and there are only a few maids and guards. Surely your father and stepmother have gone out again, working and working. You go into the house and see Jeongwoo who was sitting on the living room sofa, you greeted him but he ignored you. You were annoyed and immediately ran to your room and slammed the door, after that you immediately took a shower and decided to go out to cook.

While you were cooking, you were just thinking about how he was watching you and suddenly, you felt arms around your waist and stomach and a chin resting on your shoulder. Jeongwoo.

Jeongwoo just chuckled when you were surprised and immediately spoke in a whisper.

"Forgive my cold attitude lately my dear sister, I'm just waiting for the right time for you."

Jeongwoo said while biting your earlobe and kissing your neck.
