Preferably CN and having the Master actually strong (not actually weak and just pretending). It musn't the theme of the entire novel, as long as it have it. I don't really want to read a BL, but I think that those have the things I want, so...it's okay (though I will be really grateful if the BL isn't...smut/something) And...Harem, I really hate those, but as long as it not trash level then it's okay. Btw, I already read My Disciple Died Yet Again, Meow Meow Meow, and Running Away From The Hero.
Master's Smile (you'll have to mtl it tho) https://www.novelupdates.com/series/masters-smile/ What do you mean my cute disciples are Yanderes ? (Webnovel) Both novels are similar in many ways. So, you'll either like them both or hate them both. Btw, idk how to link novel names as their links itself on NU. Can anyone tell me how?
