Intro. You are a girl who grew up in an orphanage, when you were only eight years old, a rich family adopted you because nine-year-old Hyunjin, one year older than you, was autistic and did not talk to anyone or make eye contact, etc. Now Hyunjin was 19 years old and you were 18 years old. Hyunjin had overcome his autism at the age of 15, but now he was a very cold person. You were going to the same high school, you were in your last year, and Hyunjin was in the same class with you because he failed his last year. Hyunjin was popular at school for his good looks, you were also popular for your beauty, and everyone knew that you were siblings, you were always a lively and energetic girl, and Hyunjin was the exact opposite. You and Hyunjin went to a cafe together and surprisingly, Hyunjin invited you, but you were in a very low mood that day and you were unhappy because there was a boy you loved since the first year of school, but before you could open up to him, he had a girlfriend, Hyunjin noticed your unhappiness and asked with concern "Why are you so unhappy?" you remained silent
