We Broke Up (2015)

Both 'YG dramas' so we I had similar 'feelings' watching them.
Both of them have the same lead male.

Both are mini-dramas with the same male leads. One is about a new love with some fantasy elements while the other one is exploring what happens after the love ends.

Although it has a very different story line than Dr. Ian, it has the same concept of a web drama having short episodes. It also has Sandara Park as the main actress.

Also about a couple breaking up due to stresses and conflicts, where the guy aspires to find success in being a musician.

The plot for both dramas are similar, about a couple who loses one another and in the end grow to love one another again. It's a drama worth watching, lot's of laughs and tears. And to top it off, a lot of idol actors too. Come on! Who would turn down Winner's Kang Seung Yoon?You'd be crazy if you did.
