Imagine:

Surprising Kookie with G-Dragon concert tickets and backstage passes for his birthday and then him fanboying so hardcore before showering you with kisses and skinship because he's just that happy. 

After screaming for a while(because who wouldn't, it's G-Dragon)

"My Jagiya is the best~" *dancing around the dorm* 

And then he'd become more affectionate than even V hyung~

(imagine he is V and you are him) 

I know this is late but hey, better late rather than never. Happy late Birthday Kookie oppa!
