beomgyu is your childhood friend, you were best friends, but you had to move to China when you were both 6 years old. A whole 11 years have passed and you returned to South Korea to study there. You remembered him well and were glad that you would see each other again. You entered the class and the teacher introduced you, there was only a free seat next to Beomgyu, you immediately recognized him and sat next to him, but he was so serious and cold,he didn't remember you at all
