Radio Romance is a very simple romantic K-drama without any big plot twists or anything like that but with a lot of clichés (A LOT!!!).
In spite of that, I did enjoy watching it although as the plot progressed I wasn't expecting much honestly.
I really enjoyed Ji Soo-Ho who could make any girl watching Radio Romance fall in love with him, but when it comes to Song Geu-Rum, I don't know why but I felt like during the K-drama, in the beginning, she doesn't really show the process of falling in love with him. I'm not saying she's a bad actress because she's a good one from what I've seen from her previous work but maybe in this drama she didn't show her character's emotions that well. But, in spite of that, I felt like the couple was really cute though.
