Tricolour Lovestory S -Sunnyrain Lovestory-

It's the time for the light autumn rains, just a year before Tricolour Lovestory's events happened.

The handsome Chi Yao is invited by his father to join the student council to develop his social skills better. There, he will meet two beautiful girls: a cool, kind upperclassman that supports him whenever he's hurt and an adorable blonde girl who carries the same surname as him.

Boy meets girl, and this looks like just another story about youth, but there's more than meets the eye.
