Finally Married My Long-Time Crush

Sakura Go is a third-year high school student. She is not good at studying but tries hard to pass all the subjects. During their opening ceremony, when she was in her first year, she had a crush at first sight with a guy named Seiya Chiba. Seiya Chiba was the top student in their school. On Valentine's Day, Sakura had the guts to confess and give chocolate to Seiya. Seiya is the type of guy who is arrogant and cold-hearted, so when Sakura gives him the chocolate, Seiya does not accept it and walks away, leaving Sakura feeling sad and embarrassed. For three years, she didn't approach Seiya; instead, she secretly watched him from afar. Throughout those three years, Sakura still has a crush on Seiya.
One day, her father was attacked by loan sharks and took all his money and also their house. Sakura's father said they would stay at his friend's house for a while. When they arrived at his father's friend's house, she was shocked when she saw Seiya. His father's friend is Seiya's father. Sakura is going to live with Seiya under the same roof. Is it fate? What will happen to Sakura and Seiya? Will Sakura change the arrogant and cold-hearted Seiya?
Sakura's one-sided feelings towards the top student since freshmen are within her reach now.
