Selina said, "Do you really not know why I'm not coming back?"
Luke: "…Got it. Thanks."
Selina said, "I'll be shopping for the next two days. Don't bother me, got it?"
Luke said, "Okay, but you have to call me every day so that I know that you're safe. Also, that red-skinned weirdo can be very dangerous. You have to be careful."
Before she hung up the phone, Selina suddenly said, "Go for it. I have high hopes for you, young man!"
After knowing that Selina wasn't coming back, Luke was reassured.
If the red-skinned weirdo did come back, he would definitely go after Luke rather than Selina, who hadn't been the one to attack the man.
It would be safer for Selina if she kept her distance from Luke for a day or two.
When Luke returned to the living room, the two girls were already enjoying their drinks.
