Summary of Solo Leveling Manga Chapter 102
Sung Su-ho is born — Jin-woo and Cha Hae-in’s son. He inherits traces of his father’s Shadow Monarch power, something Jin-woo notices immediately. Jin-woo makes a decision: he will seal Su-ho’s powers and memories so his son can live a normal life without the burden of what his father is. The sealing is done through a System function Jin-woo accesses specifically for this purpose. Su-ho grows up as an ordinary boy with no knowledge of the shadow army, the war, or who his father truly was.
