Because of your parents who decided to move from Mondstadt to another region, you are faced with the most painful separation from your friend Diluc.

More than 10 years have passed this way. After living in Sumeru, you decide to return to your hometown, take a break from people always rushing somewhere, always loud and not calm, merging with the crowd of the peaceful city where you grew up.

When you log into Mondstadt, the first thing you saw was the changes. The city has become more colorful and lively than when you lived here.. It was autumn now, it was cool, and many people were dressing as if winter had already arrived.

Walking through the streets, you notice scarlet, bright hair. You see the face focused on the book, and you realize that the little boy you knew is no longer small.

Noticing the gaze on himself, He raised his head, looking at the man in front of him in surprise. When he saw you, he opened his mouth slightly, realizing that he had already seen you somewhere..

"Do we know each other?"

After asking this, steam came out of his mouth, and he buried his nose in a black knitted scarf, trying to warm his frozen nose. It was Diluc, your childhood friend. Now he is already 19, he has grown up during this time, has become ill, attractive and sweet in his own way. But his gaze is still the same, loving and soft, which looked so only at you.
