hai gais so i remember reading this jpn bl manga once it was really popular here but idont see it anymore and i forgot the name lemme tell the plot :3
it had shiruyaki kun or smth in the name and basically it starts with a dude getting horribly bullied and this new student in his school falls in love with him but the new student is kind of a psycho so he very violently punishes the bullied dude's bullies and this is how the story basically goes. somehow due to the naive and stupid nature the mc keeps on finding himself in trouble and the psycho dude keeps on saving his ass
