REMEMBERING THE TITLE

there was this bl manhwa i read and i’m sure this happened in the later chapters cuz i think their relationship was established
but they did role play and it was like “bad student good teacher” or something like that ???
and i remember mc was able to make a wish, or ml would grant him a wish and his wish was gonna be for “part two of bad student good teacher” but he ended up not making a wish or smth bcs he was content just being with ml
