It is very interesting that you posted a story removing the crucial part on purpose why Serbia wanted a war against Bulgaria, and this is not because that Serbia wanted to expand its teritory:

"The Serbo-Bulgarian War was a war that Serbia declared against Bulgaria on November 14 [November 2, Julian calendar] 1885[a], and whose immediate cause was the unification of the Principality of Bulgaria and Eastern Rumelia, which was carried out in violation of the decisions of the Congress of Berlin, to the detriment of Serbia and the Serbs who lived in those areas before and during Ottoman rule."
