This is really nice content!
I have been interested in reading these, unfortunately I keep forgetting to look up their names. xD Now I have you as a resource~

Some Shoujo I really like is Kaichou wa Maid Sama, Fruits Basket, Hana Kimi, Alice 19th, Meru Puri, Imadoki, Carcaptos Sakura, Fushigi Yuugi, Marmalade boy etc.
XD as you can see I am a bit outdated with reading manga.
I have read some of Skip Beat! I really enjoyed reading that one, but my library only had a few volumes..

I really like that you mentioned Bokura ga Ita has a Live action!
I love watching the live action adaptations of manga's .
Hana Kimi has a ton of adaptations, and all of them were really enjoyable.
There were also adaptations of Walflower, Itazura na Kissu, and Hana Yori Dango. (They were also live actions of the manga, although I haven't had the opportunity to read those manga yet)

From my experience, the live action adaptations are always fun to watch, so I am definitely going to put Bokura Ga Ita on my list of things to watch ^^

Have you seen any of the adaptations to Manga before?
That stuff is my jam xD

Anyway~ great content!
