Looking for a manga about a boy whos been trained for all his childhood so hes super strong but his grandparents who trained him made him think the rest of the world is even stronger so he thinks he's super weak

- any stories where the villainess or the revenger (?) actually goes hard? And doesn't just do the "ah I'm going to run away >m<)" or "now that I'm a different person, all the MLs are going to treat me like the heroine uwu" bullshit
- also I've already read "kill the villainess" The Villainess must die, The Way to Protect the Female Lead's Older Brother, and Beware of the villainess
