After school, it's raining heavily outside you forgot to bring an umbrella. You thought of sharing it with your crush, approaching him, you saw him leaving the school building with another girl while laughing.

Heartbroken—you existed the building without anything covering you. Surprisingly you didn't get drenched in rain water. You looked up to see what's blocking the rain, and it's an umbrella. You look besides you, it's your enemy—Marcus, sharing his umbrella with you, with a smirk he said "I won't let you get wet so easily. What if you catch a cold? Who will I annoy then?"
