Let me start by telling how this story is too long for 16 episode. It can be easily finished in 10 or less. There are lots of unnecessary details that makes this drama so boring, at the same time gave me headache.

Firstly lets talk about what I dislike about the characters. (just my opinion)

Hana is just so flaky. I understand that it's hard dealing with toxic relationship and all, believe me, I've had some share of toxic relationship. But in this story, Hana's behaviour is just nonsense. She's the type of person that ignores what her friends are saying until the rock hits her later on, which can be annoying sometimes.

Won on the other hand is a coward. Not only he doesn't admit that he likes Hana, he just has to wait a thousand years to confess. I get that he has to consider the risk of losing a life-time friendship and he has trauma, but c'mon, 17 years of friendship without confession? even many marriage couldn't last that long. What more trust does he want.

Seo Hoo is just straight up narcissistic, egoistic, and so toxic. I like that he's true to his feelings, unlike Won. But c'mon, after he left her on the engagement, basically shamed her because of that, cheats on her, broke her - and after 3 years of silence, the first thing he said was, "I'm sure you missed me?" what a d*ck. And I feel like all he said is very egoistic, like making all the talk about him, not Hana. He should've begged on his knees to take him back and explain what happened 3 years ago. If he really loves her, which I think he doesn't, he should've hold his pride and say wtf happened that day and begged for forgiveness. After all, the one that hurts the most, and embarrassed the most was Hana.

So Eun, I have nothing much to say about her since her character is just uninteresting. She's manipulative, yes. But every third person of the love triangle is always petty and nothing new. She just gets more hate because she's a woman who is chasing after a guy (what I realize in every drama).

What I like about the drama is mostly about the chemistry between 2 best friends. It's nothing new or sophisticated, but it gives me comfort knowing that friendship can last that long. And I like the compatibility between the 2 too.

For the acting, I feel like it's not Ha Ji Won's best work. There are many awkward facial expression, and I feel like her facial expression of sad, angry, and happy is just same. It gave me blank character every time.
