Hana yori Dango, Watashi no... Megane-kun Recommendations
The plot is really different between the two stories and the two main girs are different :
-Makoto takes a really long time to realise her feelings for Tsukasa whereas Chouko has always loved Megane_kun.
-Tsukasa and Megane-kun are somehow alike because they are impulsive, jealous, and possesive guys. But when they love they are very passionate.
In my opinion, Hana Yori Dango is really a classic and it is much more better than the other manga but you still can try it because you will find some similarities in the boys behaviours.
