Girls on the line

Luli has just aged out of the orphanage where she grew up, so she starts work in a factory thanks to her friend Yun. Yun is also an orphan and loves the independence that the factory job brings her: she can buy and do the things that she wants, including having a boyfriend. There are rumors that her boyfriend, Yong, is a bride trafficker, but Yun doesn't believe them. When Yun discovers that she's pregnant and then disappears, Luli tries to track her down, afraid of what Yong might do to both Yun and the baby.
