Damm, Dirty, Dumm

Tae-woo, a gangster executive who has never had a relationship because his genitals are too big, and Gyesu-chan, a bully who now owes a debt. It's okay if I touch it once, but his genitals are too big! "This can't be possible... "I was the top!" The tingling shame only lasted a moment, and Gyesu-chan gradually fell in love with Tae-woo's strange charm as well as his genitals.
