Ya Lun and Gui Gui were the sweetest and cutest
couple in high school. They were also the most
populest people in school. Every year, at there
school, there would be a competition against other schools, and they would always win. Gui and
Ya Lun love to sing so much that, whenever
they were together they would make up new
songs. They have been going out for 3 and
half years now, but they didn't know that
something was going to tear them apart? After
high school Gui left to Korea and Ya Lun stayed
in Taiwan.

What broke them apart?
Why did Gui leave to Korea?
