The complete opposites. Somehow, despite having totally different personalities, hobbies, and interest. Zion and Luke managed a peaceful and healthy relationship
Although it's mostly Zion who puts the energy and effort in it. But he knew Luke did care for him in his own way. He feels it, somehow.
But sometimes, Zion couldn't dismiss that lingering doubt in his mind. For Luke's first lover was a girl, 5 five years of relationship on top of that. He couldn't help but overthink
Did Luke choose him because he loved him? Or because he was the closest one around back then?
But no matter the answer...Zion will just turn a blind eye. For he's love for Luke was so great he couldn't even bear to leave him or whatsoever. His everything. But was he truly his?
