On September 25, one fan uploaded some photos taken in Milan on Twitter.
The photos were of Yoo Ah In and IU brightly smiling and waving at each other on the street.
Surprisingly, these photos were not taken in Korea; they happened to spot one another in Milan.

Then, they greeted and spoke to each other for a little while before saying bye and walking away.
Their smile seemed to tell they felt a little awkward, since they actually do not know each other well at all.
Yoo Ah In and IU were in Milan for 'Milan Fashion Week 2022'; although they had met at the event, they had no idea they would meet while walking around the city after the event.
It looked like each of them were just enjoying their free time with their staff in Milan following the fashion show.

They left comments such as, "Ohhhh we need their collab!", "Please collaborate soon!", "This is so cute! These photos made me smile." and so on.
