looking for this BL manga

i forgot the plot but like the MC wears a glasses with a black hair, then ML is blonde. the artstyle was kinda gray-ish but its super good. so like the MC is stalking ML trying to bring ML's life to the ground because of their past? school life? i think. But yea the MC just purely hates the ML but ML is somewhat toying w him. thats all i could remember
