Hé is afraid he will attempt to suicide if he knew the truth
I would also be afraid to tell my suicidal loved one that the only person he has left that can be called a "family" has been lying and using him since was born for his own nefarious purposes
Yep, don't tell him. Tell Minchan later when it's too late and in a situation when its unredeemable. And guess what, he now wants to be away from you. Stupid Seme.
