Brother, Am I Cute?

Si-hyuk loses his parents in a sudden car accident, and his younger brother Si-ha is 20 years younger than him. At the funeral, family members were whispering amongst themselves about Si-hyuk and Si-ha. "What should we do with those two? Who wants to take charge?" "Oh my, now that he's a college student, how would he raise his little brother?" "I heard there is insurance money?" Amidst the chaos, Si-ha spoke up for the first time. "Brother. Brother." "Uwaa!" Si-ha pronounced the words correctly and began to cry. He said "brother," not "dad," not "mom." Si-hyuk slowly approached and hugged Si-ha tightly. "I will protect you."
