I marathoned this drama, I didn't watch it week to week, so I probably got different feelings from it then the other viewers. I enjoyed every moment of this drama - it never got boring or draggy for me. The sound effects were great most of the time - sometimes they were over-used (tvN likes to over-do sound effects sometimes though). Even though this drama deals with a serious topic like cancer - it delivers it in a more "peaceful" way then a melodrama way - it was easy enough to watch and I only cried a few times. Plus I liked how the ending was telling viewers to never give up hope & live life like it's a miracle - b/c every moment is a miracle. :D The entire cast did a great job - every once in awhile I could see some over-acting going on (but I think the directors wanted it that way, so I won't complain b/c it did come across as comical that way). Lee Yoo Ri did great in her role as Cha Mi Rae, super hilarious & yet stubbornly proud... she played out every emotion perfectly! Cheers to her! I hope to see her in more dramas like this, rather than her usual "villain" type roles she's known for in her other dramas. Lee Dong Gun was great as Han Yeol, a very naïve and somewhat stupid loving man, I liked him but I also got annoyed by his "I'm going to throw everything away for love" type attitude he displayed at least 4xs on the show. Lee Re was awesome as Sa Rang "love" - it's my first time seeing this little girl on a drama and I can't wait to see more of her! I can't forget the side characters like Seo Jun Yeong as Dr.Shin (I love this actor seriously!) <expect an article about him in the future> He always amazes me with his roles and he's SOOOO CUTE ?.? (I personally think he's a mix of So Ji Sub & Kim Rae Won) anyways - his character was fun to watch as the cute clumsy doctor who had a crush on Mi Rae (his sunbae) their interactions were adorable ^-^ Seo Ye Ji as Ji Hye is also a new face to me (I think she's pretty but has an odd voice) - she was overly comical - sometimes annoying but I did laugh several times with her "over-acting" - so I guess it worked lol. All the baseball teammates did good playing their roles - especially: Choi Min Sung, Park Joo Hyung, & Choi Dae Cheol - The music was EXCELLENT! I loved every song - my favorite was "Meaning of You" by IU - followed by: "Yolo Man" by Jung Dong Ha, "Because of You" by SPICA, & "It Hurts, It Hurts" by Lim Jeong Hee, other songs that were good but not my favorites: "Mirage" by Changmin & "?" by MIII I would definitely re-watch this drama & I do recommend it for marathoning ^-^
