"Your gayness is showing." Someone whispered, and Jaebum almost, almost shrieked a not-so-manly squeal. Jackson chuckled and patted the leader's back, completely aware of his one-sided [not really, but that's what jaebum assumes] affection towards the blond. 

"Wha-what?" Jaebum nervously stuttered. 

"Your love for Youngjae's showing, dude. You're staring too hard." Jackson stated, and Jaebum almost punched him on the face for 'whispering' too loud. Youngjae might hear it, and the possibilities were endless.

Youngjae might not have feelings for the leader, and it'll destroy the friendship they have and it'll be awkward between them. Or, Youngjae might be homophobic and when he discovers the secret feelings of Jaebum, he might be hateful towards him.
