Mom Came Over the Sea

Also known as 바다를 건너온 엄마

Junsu (Ham Wonjin) wanders the streets of Korea after his mom leaves for Japan to earn money, while at home, his alcoholic dad (Kim Youngwoong) fights with him over his complications from his mother's absence. By chance, he comes across a Korean-Chinese Woman (Lee Seonjoo) who similarly has come to Korea to earn money for her family in China.
