What is the real ending of School Rumble?

I read in the manga:school rumble z that Harima and Eri ended up together and Karasuma and Tenma ended together.but a blog in another website says that in the school rumble 3,which is about to be released, Tenma heard Harima saying'i cinta anda tenma' and tenma says to harima"i cinta anda too'
so which one is the real ending?
