No, no, no. After all the web recommendations I've read about this drama, and it has turned like this? Really?
A plot that could give us watchers more laughter and fun, while our hero tries to get over this "childhood friend" status and tell the girl he loves the words she is also waiting to hear: "I like you, will you go out with me?".
But no, right? Angst and drama because both the "childhood friends" are pathetic to boot. Back and forth but back again. Never saying what's really inside our hearts and minds until the very wedding day's speech after going to the past making almost the same mistakes.
Generally speaking, the plot is good, the final product is not so "awesome" as some Yamapi fans make you think all over the internet.
The good thing: some messages that Ken had to learn through his "back and forth but back again" experience.
Some performances were good, even Yamapi did a good job in some episodes.

The bad thing: some absurd comedy that really didn't made us laugh, just sigh and say "it's almost over" (since episode 1 though).

The worst thing: Some of the characters were really all over the top. I'll explain myself better.
Ken: was too pathetic almost all the show.
Rei: pathetic all the show, sorry but I didn't like her performance.
Tsuru: do I have to say that sometimes he was so that annoying that it turned out unbearable?
Eri: the same as Tsuru, sorry.
Itou sensei: I'm really sorry for the actor who portrayed this character but, I really have seen him in better ones and I know he's a great actor, this one is forgettable.
Tada sensei: I know Naohito Fujiki is an awesome actor, he's handsome and has a beautiful smile, but seeing him smile like a dumb in each episode was really painful.

I know some Yamapi fans would say that this words are "only my opinion" and yes it is, but theirs saying "Operation Love" ("Proposal Daisakusen") is one of Yamapi's best works or a great and funny drama, are also their opinions.
