What is the real ending of this anime?

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 love آپ tenma' and tenma says to harima"i love آپ too'
so which one is the real ending?
