Hidoukou Shinaide has it, but it's not the theme of the main story. Maya's cousin, Akira's step brother (or brother?)
for the yaoi I’m looking for it was the main theme but thank you for giving me something new to read :)
Does anyone know the yaoi where the mc step brother is always stealing/sleeping with his love interests? I just remembered that it wasn’t a colored yaoi and the mc/Ike had dark hair.
