Right after the girls left, Kevin offered to buy Sasha a drink as a 'thank you' for helping him shake off the two girls.
If it had been anyone else, Sasha probably wouldn't have agreed to his offer, but because she had been hoping to see him again for so long, she couldn't let this chance slip her by.
She immediately agreed to have a drink with him. This was her chance to sort out all of the emotions running through her mind in the past few days.
However, Sasha didn't know that those emotions had been stirred up by Kevin's secret entry into her apartment as he subtly drugged her meals while hiding inside her house with the aid of his skill (Cubic Fabricated Reality).
The same skill he had used to trail Dahlia in Winterfell Park without her knowing that he was right behind her the whole time.
After settling down in the bar, she couldn't believe how they both shared the same preference.
