Those who had doubts about its age gap part should just give it a try.. Its just a love story of a kid who loved only one woman throughout his life.. Yea his love just started at an early teen and in a more or less isn't ethical form... But...

Best part:
1.STORY: Yea its true love knows no age but the way this drama shows the raw feelings of a teenagers going through puberty and stubborn yet strong feelings for a woman whom he has caused immense trouble coz of his childishness and thoughtless actions yet this kid matured up thro this process who dreamt every dream and took every step to become a capable man just to be with her ..and she who is already a grown up but still doubts herself, no confidence but a stable dream clumsy yet sensible, she restrained her every single emotion dedicated to him.. For him n herself, she avoided, restrained, ran away and lied... But no matter what she had that kid in her worry, happiness, and trouble... In a way or another, that arrogant carefree brat's words were her strength to fight... You can call her crazy? Illogical? for falling for a mid schooler... Illegal indeed... But she never took a step until she could not take any more steps back at the dead end... She was sensible and he was stubborn but both were in love and tried to forget each other... And of course, they gave us a beautiful legal ending which was a happy one...

2.Supporting Characters: This drama had some very powerful supporting character that will actually make your emotion stable and make this story way more real. First the mother of our male lead who was annoying as hell but also makes you realize what a mother is and where her fear lies... She wasn't really against his love for his teacher ..yes you read correct..she wasnt..she was just obsessed with the fact that his son might do the same mistake she did..and that made her more and more scared and she did more and more things without getting any fact straight. That obviously made a teenager go rebellious and leave home. That part was the essence that made his character more real and made the mother live a villain yet a logical person who would even go to the police to stop him. Then comes the ex-fiance, He was somehow mixed annoying and confused to me..like he was falling for a woman basically older than him too? but still could digest the same for hijiri? well, he looked more confused to me about his feelings and fears... I felt his worry about hijiri ruining her everything for a mere boy but it was way beyond his concern. Then comes Haraguchi san..one word I loved her from the moment she appeared on the screen..like she ad only she could understand hijiri even though she had no direct connection with her..and loved it how she became her support and hijiri became hers... "Hai! Sensei." that line was my favorite tbh. I almost teared up at that moment.

3. Soundtrack: Well, not being a Japanese I memorized the whole song. Yea that just amazing. When you can actually relate to every word with the story that's the best soundtrack right?

The only unsatisfied feeling was:...............
...the kiss scene.. I mean u guys gave us a mid-school kiss? A high school kiss? Then why not when he is an adult kiss? I m sure when they hugged there was a kiss but the deleted it.. Not fair.. After all those year madly in love yet waited for each other from far of course the reunion needed a kiss???????? well, it's my personal desire and feeling... XD I really wanted one... Like being a matured woman she really is far away from any desire..even our little boy feels nervous wand wants to touch her XD

Why I gave that heading? Cause of the ending.. watch it and you will find out...How the sky is related to them... As it was a common but beautiful scene and I loved how they connected them.

Happy Watching~
