In September of his senior year, with the lingering heat of autumn scorching everything, student athlete Su Nianxing has two biggest headaches: endless training and math problems that look like alien writing, no matter how he squints at them.
He thought the tutor his mother had found would be just another top student. It wasn't until he opened the door that he discovered it was Jiang Yu.
The one who had earned early admission to A University's physics department, cool and taciturn, the academic prodigy who had thrown his heartbeat into chaos with just one distant glimpse.
One room, one desk, orange soda set to the side, and a math workbook spread open.
Su Nianxing is so nervous that his palms sweat. He's afraid that being too slow will annoy Jiang Yu. But he doesn't know that across from him, Jiang Yu's heart is just as out of control as he watches the tips of Su Nianxing's ears turn red.
One is a dazzling, passionate sprinter on the track. The other is a quiet, composed competition prodigy at his desk.
The two of them had nothing in common, but tutoring brings them gradually closer.
The orange soda is sweet and fizzy, while the scratch paper fills with functions and fluttering hearts.
Senior-year problems are hard to swallow, but someone is willing to slow down and work through them with him, one by one, while catching the feelings of youth he can't keep hidden.
This is their senior-year story of secret love, sweet with the taste of orange soda.
Theme: A mutual crush between two boys. Under the pressures of senior year, they support each other and grow together. Passion and tenderness collide, and amid problem sets and soda, they find the heart-fluttering magic unique to youth.
