Lin Yujun, a level-ten social-phobe, an inner-monologue queen, and a Leo, has a secret she keeps tightly under wraps: she has been crushing on the boy in the white T-shirt from the apartment next door on the 11th floor, Zhou Yao, for a whole year and three months.
They have never spoken or crossed paths. All it takes is her heart racing for 0.3 seconds in the elevator and the light in his window coming on like clockwork every night, and she has spent an entire year dating him in her imagination. He is as fresh as grass after the rain, and his steady, reliable presence somehow makes her feel safe. He is the ultimate mix of youthful charm and dependable, dad-like warmth.
Alas, this Leo turns into a timid little kitten in real life. Every time she works up the courage to strike up a conversation, her plan falls apart the instant she sees his tall, upright figure.
And the best part? Her aloof cat, Diandian, seems to share her feelings and has become Zhou Yao's number-one fan. Rain or shine, it runs to the neighbor's door and waits there, putting on its sweetest, most innocent face!
