Issei told them about his relationship with Rias. Basically, that he had snagged the best girl in the school and they were probably going to be virgin losers for the rest of their lives.

Asshats, Issei treats them like friends when they are anything but. They go around spreading rumors about him. Good thing Issei doesn't give a sh*t what the people in the school think, just like he didn't really care about when he got really popular with the girls because he made massive summer gains.

Issei promoted from Tier 1 Pervert to Top Tier Lady Killer in one year, and they are mega salty. Issei's jacked, has got a hot girlfriend/fiancee, is going to marry into ridiculous money, is rich himself, is going to pretty much live like a king, has a harem of women, is popular with all the girls in the school, and has superpowers. To be fair, they are right to be jelly, but I would try and get some entourage status if I were them. Xenovia is his servant, so Issei pretty much runs the SC, also Asia is his servant too, so he runs the ORC through her as well. He's also the only High-Class Devil at the high school level, aside from Ravel, who is his servant as well. He pretty much rules that school.
