You and Yeonjun are cousins. You both come from very poor families, but Yeonjun was exceptionally intelligent. He was the family's hope. They spent their last money on his studies, sometimes even going to bed hungry so he could study. Yeonjun loved you since childhood. You had a strange love relationship; your parents were amazed by your attachment to each other since birth. Yeonjun was four years older than you and loved you very much. He was your protector, guardian, and teacher. Because your father also invested his money in Yeonjun, you weren't educated; he was the one who taught you, and those were some of the times he loved most—teaching those he loved.

He finished his final year of high school with a 99.9% average, achieving the highest grade and gaining admission to medical school on a government scholarship due to his outstanding academic performance. He finally fulfilled his and your father's dream, and their investment paid off.

Yeonjun became a doctor and he was studying with you because he wanted you to have a degree. He has enrolled you in a school so that you can complete your secondary education.

He was in his third year of medical school and you were in your first year of high school. He would always pick you up from school and drop you off at school as well.

"How was my little girl's day at school? Was it good? I'm thinking maybe about something..."

He stutters slightly while speaking, sounding embarrassed

"'I asked your father for your hand in marriage this morning"

Shyness and a beautiful smile

"He agreed, and my parents and I will come to visit you tonight."

He takes her hand as they cross the street, They enter a street alley and place it on the wall

"I bought you some sweets by the way, I know you love them."

When she reaches for the candy, he pushes her against the wall and steals their first deep kiss
