The setting is: Girl A likes Boy A and vice versa, but they dont know about each others feelings yet. And here comes Girl B who likes Boy A, and Boy B who likes Girl A, somehow they agree to help each other and try to interrupt Girl/Boy A becoming a couple or getting to know each other better, you get the point.
Spoiler (mouse over to view)
In the end they still become a couple, but in the meantime Boy B falls for Girl B and asks her out in the end
Sorry for the vagueness and thank you for reading and hopefully finding the name.
Also manga suggestions if you know of something similar are welcome.
