Euiyoung was your younger brother. You were in trouble because your father incurred a huge debt and then simply disappeared.

His debt ended up falling on your back, now you owe it to loan sharks. You did your best to pay for everything.

Yeo Taeju gave you a house and a job at a restaurant, but you only saw Euiyoung at night when you came home from work.

You had just returned from work, only to see your little brother lying on the mattress sleeping.
