JB
The other guys all look at him and say "OooooOoOohh", causing Jaebeom to turn bright red. The guys always tease him whenever you're affectionate towards him in front them.
Mark
After you peck him on the cheek, the ends of his lips curl into a smile and he blushes a bit. He pauses the conversation to peck you back on the lips before he turns back to the guys, though he doesn't hear anything they're saying now because he's thinking about your kiss.
Jackson
He squeals happily and as the other guys are about to tease him, he says "That's my girlfriend, everyone. Don't you all wish you had someone like her?"
Jinyoung
A grin makes its way onto his face, but he tries to cover it wit his hand. "Are you embarrassed of your girlfriend or something?" BamBam asks him, which makes him blush and defensively say "N-no, I-I just..." but he can't finish his sentence because he's still too in shock from your kiss.
Youngjae
He grins and doesn't try to hide it. When one of the other members asks him something, he doesn't answer because he's still reimagining your soft kiss on his cheek smiling like an idiot.
BamBam
Right after you kiss him, he makes sure to return the favor by quickly grabbing your arm and kissing you back on the lips in front of the other members. "Eww, BamBam, get a room", Jinyoung teases him. Bam quickly shuts Jinyoung up and goes to grab you and pull you into his bedroom.
Yugyeom
He blushes after you give him a kiss and bc he's the maknae of the group the other members never fail to tease him, saying "Wow guys, our maknae is all grown up now with a girlfriend!" Yugyeom attempts to roast his hyungs back and fails miserably, then laughs it off.
