Lol.. there is a scene with ML as a child and his omega father waiting outside the other guy's house when Ml's omega father was trying to meet his alpha father. While they were waiting his brother, the scummy alpha who is MC's ex, who was a high schooler back then arrives and sees them both. Although they might not realize, we do get to see the characters and know that the ML and the ex are half brothers..
THANK YOU
all of you who say it was obvious they were brothers from previous chapters AND I DON'T REMEMBER SHIT
