both are from 2025, but they aren't too similar except for the high school plot. I'd say the main leads are amazing, they are strong and there's a found family trope in both. They also have humor! The fight scenes are great and most importantly, the plot is amazing!

- Same concept with finding hidden treasure and a group of people finding the treasure together, working as a team
- Instead of the NIS it´s the police
- It´s interesting and funny to watch

Both are about charismatic MLs on a mission to find missing gold/money by infiltrating settings while befriending the people they meet there along the way.
