I haven't watch the anime, but I will base on my comment from the manga.
If you are planning on getting the series because its a comedy, let me warn you that its a trap or some kind of joke. The supposed comedy ain't funny, most you will get is a smile or a chuckle. I fell for it and I don't want anyone to be like me.
Source: ANNSana Kurata, a child actress, faces many problems in her classroom, including a major one - her bullying classmate, Akito Hayama. Sana's outgoing and friendly nature leads her to work towards correcting all of the problems around her. Her 'meddling' irritates Hayama but at the same time captivates him, just as Hayama's gloomy nature irritates Sana and compels her to change him. As these two opposites attract each other, they face many hardships which bring them closer to a mutual understanding.
Taking out the 'comedy' its basically a girl falling in love with this bad kid during her puberty. So, its relationship/romance storyline of a 13yr girl. I don't wanna read a romantic relationship of a girl that just started her puberty. It wasn't my thing, and I was displeased when I found out it that the rest of the volume were like that.
Ignoring those points, I guess you can give it a try and some girls might even find it a cute story - a good girl changing an outlaw into a sweet kid.
