I really enjoyed this manga. Is it something brand new and exciting, not really. It's your standard shoujo in that your couple gets together relatively quickly and then face various conflicts. Despite this, you should definitely give this a read. I would have to say this in shoujo done right. The romance is believable, the characters are lovable, the humor is great, and the conflict is realistic and not obnoxious. Besides, who goes into the shoujo genre looking for something other than cliche love stories? That's basically what defines it. haha
Personally, what i think makes this stand out is definitely the characters. I felt that they were all very well developed and it gave the story a very real feeling which was nice. The male lead is just adorable. He's the more childish type, being called a baby monkey, but it's not like that's all there is to his character. He has his occasional serious moments too. If you're sick of shoujo with perfect male leads, you'll love him. 🙂 The female lead is you're cool/cold type, but she's well rounded in that this isn't the only aspect of her personality. And well the romance between them is just adorable and awesome.
I also loved the way in which they went about the conflicts in this. They were done nicely, and were realistic conflicts. It wasn't you're typical crazy obsessed girl who's going to come and steal the guy or anything, and the way in which characters reacted to the conflicts was believable as well.
I really felt for Atsu and almost wanted them to be together at times. I think this is because his feelings seemed to slowly grow and you got to see a lot of his inner turmoil over staying true to his friend and the girl he liked. I could totally relate! I also liked that they stayed friends despite this. Poor little monkey though. :(
Also, the classmates are hilarious. I laughed so much at the reactions to the "idiot couple"
The ending was nice too. Not you're typical everything in the world is now perfect ending, but still satisfying. It ended the way I wanted it too. 🙂
Basically I was happy that the conflict with Haruna's family was never fully resolved, but seemed to improve. The way it was depicted throughout the manga, it would have been unrealistic for everything to be perfect in the end with her fam, so I'm glad that didn't happen.
