im pretty sure its a manwha The plot goes like our mc had to retake a yr of school? (maybe of health issues or family stuff) and the ml is his classmate, and at first he thinks the ml is younger than him but it turns out later that the ml is actually older, but they somehow start sleeping together n i think its abit dub-con. the ml is abit crazy. abit yandere n i think i stopped reading cuz the smut was abit overwhelming. but anyways i would like to find it again. and i thinm the mc personallywise was pretty friendly, not super shy or anything thats all i . i hope someone can help! ty 74r60
