Comments: OKAY. This drama is the best I've seen in a while. I cried in the parts near the end. It was very sweet in the beginning. Dont wanna spoil anything right now. Anyway. It is a new drama. Cho Bo Ah plays an adorable character and I love her. There are so many times when I wanted to smack Yoon Jin Ah in the face with a frying pan.(Moe Othman-youtuber reference) Like seriously. AND TILL THIS DAY I STILL SHIP KIM HAN NI AND KWON SHI KYUNG. I dont give a flying fish if Ha Ni is with the other guy. I DONT CAREEEE. I ship SHi Kyung and Ha Ni waaaay too hard. And it never letting go. okay? okay. 

Anyway. I cried so much at the end. 

1. Poor Shi Kyung :(

2. Ha Ni ended up....dissappearing...

3. THERES NO EPISODE 11-16

Reason 3 killed me. But sadly they had to end it early. There were alot of holes as to why Yoon In Ah became less y and . Like someone explain this. 

Overall. This drama is a MUST watch :D
