The fact that all of this Author's works are not smut except for December

The novel of this was r19 but we comic wasn't idk maybe I'm mistaking it for another manhwa

Samk works have great amount of smut along the plot and this one also have fair share of smex, just not sure how much of it will be illustrated ⁄(⁄ ⁄·⁄ω⁄·⁄ ⁄)⁄
