In their second year of high school, eighteen-year-old Lin Jin'an stumbled into the world of sixteen-year-old Lu Xiheng. To everyone else, he was an “iceberg,” cold and hard toward everyone, only letting a few close male friends see a crack in his armor.

As time went by, the iceberg quietly melted, and the feelings the boy kept hidden in his eyes gradually spread through the years.
