[Adrian's POV]
He didn't know there's a much-complicated connection between Johan and Russell than just being in a joint family unbound by blood. They're each other's support from the failed love they couldn't let go of; Johan from his best friend, and Russell from his dead girlfriend.
Family.
Lovers.
Friends.
Enemies.
They fit neither of those categories, and yet Johan seemed closer to Russell than his actual family. They're as intimate as lovers do; knew each other more than anyone else like friends, and they got on each other's throat like enemies. There's a distinct line that kept them from being family, friends, or lovers.
As Adrian watched them bickered in the kitchen with what to cook for breakfast, it made him wonder if Johan's father didn't marry Russell's sister. Would they have become lovers by now?
