Granted Irina already has it rough, she was in love with this boy since childhood only to return and find out he thought she was a boy and has to compete with a dozen other girls. In fact, even her status as a childhood friend seems to give her absolutely no advantage, which is amusing because usually that gives a heroine an edge in these kinds of stories.

Likewise, if Issei actually gets Roygun and Gabriel, I'm pretty sure Rias is going to have a heart attack. Even if Roygun was a cheater, she is still considered to be one of the most beautiful women in the Underworld alongside Grayfia and Serafall. Plus, Gabriel is the most beautiful woman in heaven. That puts quite a bit of pressure on Rias.
