I (26) got a date tomorrow with a hb8 (21) she's an incredible dancer, violonist and opera singer from a wealthy family

So while partying I met another friend of her hb4 (a repulsive fat smoker)

Then last week we were having a party and as I'm a party promoter I was asking hb(8) about hb (4) and told her to bring her to the stuff i'm organizing. She then shittested me "oh are you interested in hb4 ?" And I answered ironically by AA "yeah I totally fell in love with her"

Fast forward tonight (friday), i got a date set up with Hb8 tomorrow (i bring her volunteering in a homeless shelter with me and then clubbing). She just texted me

" Would it make you Happy if I ask hb4 to join us tomorrow ?"

What would you guys answer ?
