it’s a classic daddy daughter manhwa and the duke or whatever was gonna adopt a girl but she needed to go through a special test, and the test was in a room and she was all like “this is a piece of cake” and the instructor guy was like “omg no way how?! this is impossible to solve!!” and then it turns out the instructor was evil and was hiding bodies or something in that room behind a bookshelf and he thought to himself “thank god she didn’t (instead doing something) or i would have been found out” also he had long white hair. please guys anyone please i need to know or i will die!!!!!
