Cuteness overload!
It's Simple :
Super Duper Adorable, Cute & Sweet, Warm, Fun, Weird, Light-Hearted.
Off-course imaginable only in a cute manga setting,
..Although..the female lead; her simple hearted foolishness withdraws us from thinking seriously about stuff, which we probably should have, she is a simple girl who just does what her heart tells her to do.
The male lead is too noble to comment on, he is like a Buddha out of a manga Hero, ..should I say Manga Buddha?!(no offense intended) hmmm ..he is too young & innocent, brave, wise, skilled, disciplined, respected, good hearted, beautiful (yes beautiful!), and handsome yet strong willed; all around Hero and Crush Worthy .. off-course totally drool worthy as well but oh, he is too young :D Yap ! he is Perfect, so we have to forgive our simple minded heroine for all her falling head over heals can't stay away from him attitude! <3

......the criticisms for the story are simply wiped out in my mind by its sheer straightforward foolish simplicity and all encompassing hilarious weirdness (characteristic of Jdorama manga adaptations I have watched previously) which somehow makes it refreshing and oh so sweet..weird, foolish, sweet ...and totally adorable. its not possible to talk more about this without going into some plot details so I will skip all that.
Spoiler.. ............Its as if the writer is saying; 'keeping it simple , the parents simply are that understanding and letting go', not going into their own pain and concerns, off-course with a son that genius, anything is possible in the future, right!! (I suppose they thought like that?! .......there! had to get that out of my system haha)

This is NOT a serious drama though, so let go off "we wouldn't actually necessarily support this in this way in real life. " when going ahead to watch this, but you probably won't regret having done that.

Only one thing remains at last; The chemistry of both the cutesy leads, is 'Cute & Adorable', yet Warm, Sweet ..heartwarming and pulls you in, cheering for them hard, despite everything, even intense in a way..something that is very sweet about it, is also very intense.
The setting is..quite creative & fresh, it looks like its been done before but its cool & different in a way. Its is actually a pretty creative storyline, in its light heartedness.

Spoiler_ish.........Not only does she herself falls in love in a decisive yet uncomplicated way in an instant, She pulls his heart in and makes it all mush for her, before he knows what hit him, simply by her sincere innocent unconditional love for him. not to mention he is totally intrigued by her before even realizing who or what she is.

One track mind simple sweet love and romance are centre-points of this, in a weird foolish Warm way. Its just fun, cute and lovable. "Love can conquer all" in a simple, creative, light-hearted way.
Loved It!

Did I say Super Duper Adorable, Cute & Sweet enough?!! Yap!
probably..no, definitely gonna re-watch again when subs for last few episodes come up

(I had to edit this twice, after loosing what I wrote earlier, so, apologies if its repetitive or not to the point appropriately )Also, thanks to MyDramaList Article "Love is the air, Jdrama style" that recommended this, I would probably have missed this if not for that
