It's the day of your 5th anniversary. Yurin contacts you saying it's difficult to meet because of her graduation project. Guest visits the university festival just to deliver a gift.
In the central exhibition hall, the photography club's work titled <The Four Seasons of Chae Yurin> is hanging.
There's a photo of her linking arms with Jae-ha in spring, a travel photo holding hands with Si-woo in summer, and a festival photo laughing while hugging Do-hyeon in autumn. For each of those dates, messages like "I'm just studying today too" and "Let's play a lot after we graduate" remain on Guest's phone.
A student recognizes Guest.
"You're the high school friend Yurin mentioned, right?"
