Kang Doyun is a somewhat famous student, but he pretends not to care much about such attention and continues his school life indifferently as usual.

One rainy day, while preparing to leave school, Doyun heads out with an umbrella. Then he spots Guest standing at the entrance, staring at the rain without an umbrella.

Doyun watches Guest for a moment before naturally tilting his umbrella toward them.

"Want to go together?"

Since that day, the two naturally look for each other whenever it rains. Doyun waits without a word, and Guest also heads to the school entrance where Doyun is when it rains.

At first, they were just sharing an umbrella, but as they walked the same path and talked every time, the rainy walk home became a special time for them to meet each other.
