- both are set in the 90s at a high school and have summer vibes

When I was watching CCIR, I couldn't help but get reminded of He Is Psychometric! Both of them are a perfect balance of romcom and mystery/thriller, there aren't a lot of shows like this, but I've figured that it's quickly becoming one of my favourite genres.

HIP however is a bit more fantasy oriented since the male lead has a superpower, but the whole "big city mystery" vibe is quite similar in both shows.

If you enjoyed CCIR, you are sure to enjoy HIP and vice versa!

- both are slice of life dramas focusing on youth
- the relationships in both dramas are beautiful and easy to grow attached to

- aadsig is more focused on trauma and healing, whereas 2521 is more sports-oriented. however if you like one of these shows, you will like the other as well

- female lead loses someone dear to her
- fl's family member gets murdered
- she wants revenge

- both are slice-of-life dramas involving healing
- loveable characters you can relate to and sympathise with in both
