I'm not being nice about my ranking, I literally think this is the best drama I've ever watched, Kdrama OR Jdrama. The story plot isn't predictable but nor is it unbelievable. It's REAL. I think that's what I like the most. The development of the characters and story captivates you and the actors and actresses portrayed those characters amazingly. I wasn't tempted to watch this drama by the description or the title, I was just bored but I'm so glad I did! I joined when it was on the 9th episode and literally had to stop myself screaming in frustration while waiting for the next episode. It has an addictive and completely lovable quality. I wanted to rewatch it before it was even finished and it would be one of the dramas I would pay money to buy on DVD and watch again and again. The music was perfect. Literally perfect. It fit the story completely. The main song Hikaru e by Miwa [Theme song] is full of hope and encouragement and I literally have had it stuck in my head for weeks while reminiscing on the last episode. For someone who doesn't ever speak while watching a drama [crying is a different matter] I found myself ragging when bad things happened, squealing in joy at the cute little moments that the main characters shared and sprouting swear words when things didn't go the way I wanted [For example; some of the interactions with the romance]. My official number 1 must watch drama of all time. Don't questions 'should I watch it?' Just. Watch. It. Trust me
