Yae Sakura/Dream Ladder

When Yae Sakura was a child, the day she looked forward to most was the time when the caravan entered the village. They will bring many rare and exotic items, among which picture books painted with strange colors are Yae Sakura's favorite. Although she couldn't afford it, the big sister of the caravan would still generously lend it to this beautiful little child.
At that time, Yae Rin was sitting alone by the stream looking at the picture book, and just opened it and took a look, then hurriedly closed the album
"Oh, big sister is here..."
That was a scene that little Yae Sakura had never seen before. On the screen, the woman in the snow gauze tutu and the man in the suit and leather shoes seemed to be signing some kind of ritual. But the overly intimate action between them couldn't help make Yae Rin flushed.
It was not until a long time later that she learned the truth from the big sister of the caravan. It was a freeze-frame scene when a Westerner took the oath of marriage. This incident left a long impression in Yae Sakura's mind-
"It turns out that Westerners will kiss each other in front of everyone when they get married..."

For Yae Sakura, she has always thought that she isn't worthy of God's favor. And the extravagant words like happiness and marriage are bound to have nothing to do with oneself.
Perhaps it was a coincidence. One year, a girl in the village was photographed by a local dame, and Yae Sakura also played the role of escort. When accompany the bride to try on the dress, the unpretentious Yae Sakura seemed a bit out of tune with the festive atmosphere of the crowd. Everyone who noticed this asked Yae Sakura to try on the dress together like a booze.
After a short thought, Yae Sakura, who couldn't help but chose a Western-style wedding dress that was completely different from the bride's Oriental style. When asking for the reason, she only replied indifferently:
"I just saw it when I was young and I was a little curious."
However, with the help of the clerk, when Yae Sakura finished changing her outfit, she felt a huge strange feeling.
"This shoe, I feel-"
Before she finished speaking, she twisted her ankle and thumped her knees before everyone.
After she returned to the village, because of a bruise on her knee, she was even mistaken for being in danger during the guarding process.
Later, when someone curiously asked Yae Sakura how she felt at the time, she just slightly loved her brows and said faintly-
"Knee pain"
