First of all, I really like this drama. It gives me a bitter sweet vibe.
The rekindling of the feeling of first love, the friendship,the family dynamic is so interesting.

I will say my favourite character so far is Jang Mo-eum. She's has a very charming personality. She's kind and brave, she knows what she wants, she the best friend you could ever wish for. She is very supportive of her friends,she seems to be open-minded too. Their friendship is so precious!

Baek Seok-ryu is strong and independent. She works hard, even when she was trying to find her dreams, I would say she is very dedicated. Her family dynamic is pretty interesting.
I wouldn't say her mother is a bad person but she really did annoyed me in episodes 7 and 8. What does she mean her life is a failure, and want Baek to live a successful life. The father too thinks he's a failure. When Baek confesses she wants to cook, that it was her dream, both her parents were furious. The father and mother is projecting their life experiences on Baek.
I feel like they don't say what they really want to say and are just be passive agressive with each other, it's just building hatred.

I don't understand why her mom wants Baek to get back with her ex. Like Baek can live a successful life in Korea too, why would she return to the US and relive all that stress. I really don't love the parents much, they are kind of annoying.
I mean I feel like Baek dealt with her sickness alone because she felt it was no big deal. She could handle it because it's always been like that.
She is unable to show she is hurt and suffering, even with the ex, she refused to explain the reason why they broke up. She doesn't know how to rely on someone or ask for help, maybe she did with her ex before he cheated.

I really understood Choi, imagine finding out your closest friend had to suffer alone as she was ill. She should have told her family and her friends about her illness. And why the heck did she tell her ex to hold onto her and not Choi. Why must she bear all the hurt and suffering alone, she doesn't deserve that.
I hope she learns to lean on her friends more, forget about the parents, I don't think she'll ever lean on them.

But at the end of all the characters are very complex and have their flaws. Let the miscommunication and misunderstandings marinate and spice their lives up!!
