Reaching a period of life where they are neither a child nor an adult, 12-year-old Hanabi Ayase and Aoi Yui meet with life-changing events. Due to the mischievous demeanor of her male classmates, Ayase does not think highly of the opposite sex. However, her perspective begins to change after she is paired with the kind-hearted Takao Yuuto for a class assignment and unexpectedly shared their first kisses with each other on the school rooftop.

With her best friend discovering love, Aoi yearns to seek her own. She finds herself falling in love with the rash Kazuma Hiyama after protecting her from a rejected suitor who had talked behind her back.

12-sai.: Chicchana Mune no Tokimeki follows the four in this phase of adolescence. As they grow up alongside each other, this sweet romance depicts the innocence and excitement of first love.

First of all, this is a kid's show so don't even try to complain anything, im pretty sure the author/director knows what's he/she is doing so don't listen to these people that disagree.

If you're looking for more anime like this go to ciao ...

So did i like it? Not really i found it pretty boring. Would 10-12yos like it? Probably, this is what i would’ve loved to watch then.

This is the sort of 12 year old i would’ve wanted to be like, not some weirdo, who still hasn’t been in a relationship at 15, so from that pov i guess it’s not too bad a show. But comparing it to all the others romance anime’s i’ve watched it’s pretty bad.

I’ve never had these experiences irl but i’ve wished for them and i guess this anime shows experiences that could happen, maybe that’s the charm of it, ...

Recommendation: Skip it unless you have the highest possible tolerance for corniness and overly-sweet sentimentality. This review covers both seasons of the full length anime, not the original short OVAs.

It feels like it was written for the actual demographic it portrays (middle school-aged girls), rather than for otaku voyeurism. Rest assured, there is nothing in this series that could possibly qualify as objectionable or creepy.

+ Convincingly portrays the transition from childhood to ...
