What 深淵裡的螢火 Is About
Some shows are made to be savored slowly. 深淵裡的螢火 is not one of them — this is a breathless, cliffhanger-hungry ride built for binge watching.
Let us talk about the story for a second: 父親早逝後，蘇洛跟著母親住進繼父于承澤家，從此人生墜入深淵。十八歲生日那晚，繼父竟對她伸出魔爪，危急時刻，是毫無血緣關係的哥哥于淮破門救下她。
于淮總是冷著臉要她離自己遠一點，背地裡卻放棄大好前程、輟學打工，默默守著她上下學，替她擋下所有欺凌與傷害。可親生母親為了討好丈夫，竟一次次將她推回火坑。
直到蘇洛考上政法大學遠走他鄉，她終於學會為自己而戰。多年後再度重逢，繼父的惡夢捲土重來，母親也在最後一刻用生命結束這場悲劇。
走過漫漫長夜，蘇洛才明白，那個從未說過愛的人，早已用整個青春護她周全。他是她深淵裡唯一不曾熄滅的螢火，而這一次，她終於能迎著光，走向他。
