She has know idea about the meeting at all would be out of character for her to be ok with that kind of conflict but in character for fuckbois superiority complex he has as well as his narcissistic personality and last he monopolized and isolated Sakura by doing that. There was no issues with her until mio and nagi came back into the picture. Kinda ironic that they may breakup after a toxic personality egging sakura on comes into the picture seeing as that's how he stole Sakura away from shionbu in the first place. If that happens then we will be keeping with the theme that anyone who comes after Sakura gets a visit from karma.Half of this was my inner pessimist writing. I don't think Sakura knows at all about their meeting or it was fucboi's idea and at that point she didn't care enough to refuse given the pacing of everything.
