Nam Woohyun and Kim Sunggyu.
They were known as two sexy singers and strange personalities and auras.
Woohyun was a greasy fellow with a great body. Usually arrogant but good-natured nonetheless. He is a "bottom" in denial.
Sunggyu was older than him, and tops him all the time. He can nag and is always teased for his non-existent eyes, naggy preferences, grandpa-like aura, and pesty lisp.
"That girl is a total Sunggyu, you can tell she is a nagger and wears the pants."
"You're cheesiness is worse than Woohyun. Don't make me your Sunggyu for your WooGyu-ness!"
"WooGyu ruins my OTP-List!"
