This was an enjoyable way to spend two hours with a cliche, but well executed storyline.
I thoroughly enjoyed this, it had me feeling all kinds of emotions, from laughter to sadness and all in between.
It's easy to watch, the characters are quite organic and there is chemistry between Lee Seo Won and Han Seungyeon.
I also liked how even played by Lee Seo Won, both Dong Joon and Sul Woo are portrayed to be two different people and it's done well to me.
Seungyeon's character was cute and peppy despite her terminal illness, which was probably the weak part for me, though I felt in the same breath, it made her more realistic, and taking her diagnosis in her stride.
Although it was cringy at points, I expected this and thus really had a good time getting into this story.
I would definitely rewatch again.
8/10.
