I understand not wanting to out the MC, and letting him come to his own terms, but I do find it uncomfortable the way they went straight to the BF instead. They basically just demanded confirmation of the MC's sexuality by circumventing him. And whatever test the family put the ML through, I feel that the MC has the right to know since he's at the center of it. The MC is a grown man and the conflict centers around his sexuality and him taking this big next step in life(moving out).
While I get that this MC is supposed to be very 'baby' and thats how the ML and the family treat him, this is the first time this story has actually irritated me with how they dealt with him.
