And another thing, it was really hard to tell if Irina had feelings for Issei at this time (most fans assume just she did), like in the gym closet, she showned no objection to Xenovia Asia having sex with Issei but where they do it, hence no signs of proper jealousy.

Athough I think she might have said it like that as to covered up her jealousy at the last second and secretly really did mind that they would do it and was glad that she interupted with a proper excuse..
