原来毕业季就是分手季
[yuán lái bì yè jì jiù shì fēn shŏu jì]
The meaning behind this is "it turns out that graduation season is break-up season", implying that graduation, which should be filled with happiness and achievements, often brings farewells in various forms, most notably break-ups of couples who are leaving each other because of different paths chosen for further education or career development after schooling.
