How did you get all the avatars you used? What's the story?

I have a favorite ex. I have a pair of cartoon lovers who like it very much. They are Oreki Houtarou and Chitanda Eru in the ice. I always thought we were like them. He is as clever and cold as a broken wood, and I am curious about everything a thousand times. Now this portrait is a portrait of the Bingguo couple, and I used half of it. It's just that we broke up before he could use it.
