+ It starts fluffy and funny!
+ I fell for Milk the second I saw him. u.u Kim Seong Hyuks acting stole my heart. x.x Wanna see more of his work!
+ It's really easy to tell at first sight who is the dog and who is the cat. The actor did a really good job portraying the pets behavior.
+ The chemistry between Milk and Uncle is fiiiiire. I loved their scenes together!

Dislike:
- Tbh I found the story between Jungwoo and Choco a bit boring. I couldn't bring myself to like Choco.. I am just someone who likes people like Milk more than someone like Choco. So this whole being that clingy and affectionated didn't catch my sympathy. I just waited the whole time to see more of Milk. x:
- The story is a bit flat. Especially towards the end it feels so dragged. I don't really have a problem that they don't explain how the whole coming-back-thing works, but it would have been indeed interesting.
- I don't know what to think about season 2. I'm happy to see more of their work, but actually I just wanna see Milk and Uncle looking at each other lmao.

Overall I don't regret watching it. It's short, fun and I am absolutely not sorry for being mad in love with Milk. :')) I can agree on other people's opinion about the production, the flaws and I am also a bit unsure what to think about the preview for season 2, but I'll just give it a try. :>
