A Lesson for the Arrogant Younger Brother

“Hyung-nim, you act so stiff and dull, I can’t help but wonder if you even have a cock.”

The arrogant younger brother, Yeon, always belittled his elder brother, Kangwoo.
Calling him a dullard, a beast… that sort of thing.

Yet Kangwoo, the adopted son, always responded with a gentlemanly smile,
accepting Yeon’s insults with quiet grace.

But one day—

“You always treat me like a beast, or worse, a eunuch… Aren’t you curious what this beast is like at night?”
“…”
“Shall I show you my cock?”

For the first time, Kangwoo responds to Yeon’s provocations.
