What's your favorite trope

There are multiple traits in all genres of anime like in Isekai with Mr. Truck-Kun himself, enemies to lovers in the Romance, John in every Shonen like John Kaisen, and more. My question to you is what is your favorite trope or a unique one that isn't often acknowledged. Thank you for your time if you are reading this and have a good night if it is night for you like me right now. Also I'm Upvoting/liking every comment just like all the big Posters. :)
