If you were looking for Season 3 of Age of Youth this would fill the gap!
Created by the same writer, there are a lot of similarities and undertone references

Gives off the same vibes, where all the characters are intertwined with each other because of one person who grants them wishes that come with consequences.

Written by the same writer, it has the same feel and humor while solving cases. The main FLs are a bit out there at times but relatable. If you end up getting put off because of them, they do get better over time!

If you liked Park Eun Bin's character Song Ji Won in Age of Youth, you'll like Dear My Room. The main character is basically the embodiment of her, a bit loopy at times.
