Story: For the first 3 to 4 episodes I it moved along very well. It was like two different halfs of this drama mainly because of our main character Sakuto was two different versions of him. I loved Sakuto in the first half of this drama, he had a child mind while he was still an adult. Even though he was still like a child, he had a big heart and was sweet. Sakuto wants to become smart like everyone else but the way he becomes smart is just wrong. Sakuto taking the surgery and becoming a new person and also having new "friends", was not what I would enjoyed. I feel that he took the easy way out, I would have prefer the whole drama be progressed of Sakuto becoming smarter each episode but there was a benefit of he becoming a genius even though I didn't care at all for that person. It also doesn't help that your two main characters Sakuto and Haruka become jerks later on.

I wish they stuck to one major genre for awhile because the genres of this drama didn't make me feel anything. I think they should have capitalize on friendship for the majority of the drama. I really thought romance wasn't needed in this drama but they had to put it even though I didn't feel for it. All that science/medical stuffs damages this drama. I would have just gone with drama, friendship, life, and family. Sakuto works at a flower shop and whenever he delivers flowers he could have interacted more from these people who are ordering these flowers. He could have solve some of their problems show what a flower really means or learn from them. The employees which are all men who are mostly e x convicts, Sakuto could have used his childishness mind to change them somehow. He could have developed good friendship with most of them but nope they don't grow at all. I wanted to see Sakuto grow little by little so he could show his family that he has become smarter and not a child still instead they liked him better as a genius but from now on he can't see them again because he is back to the old Sakuto.

Then that ending kind of made me finished with a smile seeing how we are back to where we started with Sakuto back having a child mind but he works somewhere else. I would have felt so much happier that Sakuto ends up with his two best friends if they made them the main focus.

Acting/Cast: Yamapi is one of my favorite actors but this drama was not one I was highly anticipated of and I was right. Yamapi was brilliant as Sakuto with a child mind because it wasn't the normal Yamapi acting, it reminded me of his Nobuta Wo Produce acting. The sad part is that when Sakuto turns into a genius, Yamapi's wonderful acting disappears back to normal Yamapi. I say the first half of this drama Yamapi was the best actor but the second half will go to Kubota Masataka. I like Kubota's character because he actually changes from the beginning to the end. Everyone else felt just bland.

Overall: I liked the first half of this drama. I just want to pretend that the second half of this drama never existed. At least Yamapi played a different character than his other roles for awhile. Other than that there's not much positive things I can say about this drama.
