Alright, as I told SuperW on Patreon... I still don't like Irene but I have warmed up a little to her. So I've shifted a few points toward neutral with her.
To add to that though...Irene's in love (maybe?) with the dad, has been partners with the dad for awhile, has seen how the dad treats the MC for the same length of time, and (as far as we know) has never objected to how the dad treats the MC. Irene also is not wonderful in how she talks to the MC. However, if over time she further warms towards the MC I could see having a civil relationship with her but she's not a redhead or brunette so she can continue to fuck the dad, my MC's dick is too good for her.
