Any bl where the MC/ML hides his strength/power/potential or he has any secrets that he doesn't want to reveal due to some reasons. Thank you~
Zhanxian - Even at the end of the novel most people don't know how powerful he is. He has always hidden his power to destroy the sect that is responsible for his and his masters death in his previous life and also for the destruction of his own sect. Solo Leveling Otherworldy Evil Monarch - hides his strength at least in the beginning half of the novel Godly stay at home dad - I think. It's been a long time since I read this.
