I've recently been rewatching FIYS and found myself finding the shows extremely similar. The storyline itself is quite different but it's more about the actual vibe of the show that makes them so attractive.
- both a workplace (FIYS is a gaming show tho)
- side characters very entertaining (ABP ppl who work there and FIYS the other ppl on the zgdx)
- very addictive
+ FIYS is definitely slower paced than ABP but it builds up nicely and don't get bored quick

I rec you sit through abt 6 eps before you try and drop the show, ofc it's not everyone's taste but it's a nice exciting watch :)

I recently finished the best of you in mind and it reminded me a lot of weightlifting fairy.
they are both knew each other from childhood (but in the best of you they knew each other way longer).
the male lead also does sports.
they are both in university.
overall you'll have a great time watching these dramas.
