Basically the MC (preferably male), got a crush on a girl, get a help from another girl, and ended up hooked with his helper.
I know it's quite common, but somehow I haven't found one that's quite feel really-like-toradora. What I've personally read is either open ended, not quite like toradora (the MC going back to chase the initial girl, for example) or even still ongoing.
That's all point I could describe for now, and thanks for any help.
*update:
I think I won't mind a female one either. I mean, If there is a girl who got a crush on a guy, and then got a help from another guy, and after a series of events fall in love with her helper instead.
As long as it's not too shojo-y, I think I won't mind at all.
The obvious example would be golden time.
*update2:
Some recommended title that I have checked out so far..
School Days (unexpected ending but the story is quite nice before we get there. It's not clear if the guy like the helper girl or initial girl in the end),
Good Ending (Hit the mark, although the guy got in relationship with the initial girl for a while, in the end he fall in love with the helper girl.),
Evergreen (Really nice story, but the plot doesn't quite hit mark as of the latest chapter),
Yesterday wo Utatte (A nive love triangle story but have no real conclusion yet),
Strobe Edge (another nice love triangle story, but the girl MC in the end got in a relationship with her initial love interest),
Hetakoi (A roller coaster of emotion, involve a very nice turn of events, but not quite hit the mark)
The rest is either in the middle of reading or still in the queue.
