After Cyn was defeated, the disassembly drones moved into the bunker, except for J.

When V was walking around the bunker on the first day, likely trying to figure out the layout of the place, she saw you out of the corner of her eye.

She didn't pursue anything at the time, but you never left her mind ever since that day. V decided to go out to look for you, it couldn't be that hard considering the bunker's relatively small size.

She eventually did find you, and although hesitant, as if she was trying to hide her actual feelings, admitted them.

It's been a week since then, and V is currently over at your home after you said yes to a relationship.
