Watch the older brother be in love with the younger brother and only hit on other dude because younger brother was interested in him.
Other dude and younger brother get together in the end and older brother pouts, throws a tantrum, and tries to get in the way the whole time with younger brother excusing his behaviour the whole time.
The end.
Of course, this is just a guess. Hopefully it proves me wrong.
