A great job as always,
@Lafarin. Thank you for you work on this hilarity in manga format. However, I don't agree on the points for you to dislike Irene:
1: Poor girl is desperate. Those three must boicott her attempts to make female friends so hard
she has to beg a girl who can (barely) put up with them. That's kinda sad, to be honest.
2: Same as above, but I think she also needs someone to vent on and who can make a "girl's day"-kind of shield against them. I don't know if it would work, but she's at her wit's end.
3: As some other commentators pointed out, she must be sooo used to them arguing betweem each other and not listen to her at all, that she must have given up. At least sending her cognitive ability on vacation leave no registry of their nonsense.
4: No problem here. Nope, none at all. If anything, I'm surprised she can get away with that amount of cleavage, but I've seen worse (read: better) in similar settings. So carry on, Irene.
Seriously, I think Irene is along with Rururia one of the most pityful characters in this manga. Not only her fiance is cheating with another girl, but also has to deal with these three stooges simping day in and out without being abe to stop them. #sadlifeaf
