TREASURE is the best! You should totally this if you are a Treasure Makers (Teume) or even if you're not. If you want to stan them and also want to memorize the members names, watching this drama is a great way to do that.

Story: [I tried not to spoil it but don't worry it's just a minor spoiler]
The story was great and every episode, you would suspect different members. That's why it's great because it will make you think who really is the ghost? (Even though it was soo obvious and was revealed that the ghost is _____ in Ep. 3, it will still make you have doubts if he is really the ghost) Also, the ghost' story was really sad and everything he had been through was also sad. Even though not everything has been cleared, it was still a great story. It also taught us that friendship is really important, like how the ghost disappeared when everyone ignored him and how he has back because his friends stand up for him

Acting/Cast:
They are amazing and talented idols and now they are great actors. Ever since I watched It's Okay, That's Friendship (Treasure 1st drama since debut), I wanted to see more of their acting. They weren't perfect that time since it was their first time but now they've improved a lot. YG be making their artists into great actors/actresses.

Music:
Their OST BFF is really amazing. Even it wasn't promoted but it's topping the charts, it shows how great it is. Choi Hyunsuk wrote the lyrics and he deserves to be called one of the best lyricist.

Rewatch Value:
Since it's not that long, You can binge watch or rewatch it anytime since it's only 2.6 hours. Totally recommend you this short web drama. You can rewatch it if you still haven't memorize the members yet.
