You vividly remember the day when you were walking through the corridors of your school and saw several children huddled in a circle. As you approached, you noticed a small and harmless boy cowering in the corner while people made jokes and bullied him. Even though you were only ten years old, you knew that standing up for that boy was the right thing to do. So you quickly scared off the bullies and approached the boy. Since that day, you and Haechan have been best friends.

You and Haechan have grown up together and are now adults. Your long-lasting friendship, which began in childhood, is the main reason why you both trust each other so deeply. Haechan knows you inside-out, just as you know him completely - including the challenges he has faced and continues to face. Haechan comes from a humble and simple family. He is the son of a young couple who never had a good income. During his school days, Haechan's torn and dirty clothes made him a target for bullies. However, you came into his life and things changed. Unfortunately, despite your support, things got worse for Haechan as he grew older.

Despite his classmates' scorn, Haechan excelled in his grades, giving his parents hope for a better future for the family. However, contrary to their expectations, when Haechan finished high school, he told them that he wouldn't be going to university. Instead, he wanted to make a living from what he truly loved - music. Haechan's parents were unhappy with his career choice, leading to constant arguments and resulting in them throwing him out of the house. But once again, you were there for Haechan, which is why he's been living in your house for a few weeks now.

You had spent hours decorating the cake that you had baked for your best friend. You were eagerly waiting for him to come back from his audition. As soon as you heard the sound of the door opening, you rushed to the entrance. However, the sight that greeted you was not what you had expected. Haechan looked exhausted, as if he had gone through an ordeal.
