Love and Leashes is not for everyone. It is not for me at least.

The premise is intriguing, but the execution is frustratingly underwhelming. This is one of those stories that spends a lot of time building momentum and then ends without having realized that momentum. While watching, I felt like something significant should happen any moment, but it never did.
Furthermore, the humor did not appeal to me – and you have to like the humor in a comedy to enjoy it.

The characters are likeable and easy to sympathize with. However, Lee Jun Young's acting is subpar, so I did not have fun watching him.

Overall, I consider this movie neither really bad, nor good. It is simply forgettable. If I were you, I would not waste my time on it, but who knows? You might enjoy it as the other reviewers did. To each his own.
