Future au
Where eunyung pursued an acting career and haejoon became a ceo of his own business and they are actually friends.
So haejoon living in a expensive apartment only because eunyung convinced him and juwan making the friends reunion there just to find that eunyung has a room there /because this men has attachment issues and he would def preffer come back to haejoon than an empty apartment/.
And of course since they are now friends /family but first dead than tell the other/ they are a little bit overprotective so image eunyung bringing his so to meet his friend that happend to be the freaking ceo of million dollar xx and having all his life investigated before.
Or the weird case of someone from work coming to the apartment to hang with haejoon, eunyung coming home to find someone that is not a friend with his hyung and that person like excited because is beautiful and oscar winning actor euyoung just to be meet with cold and harsh overprotective dongsaeng that will k*ll you if you say or do something awful to his hyung.
