He’s the nerdy guy in your classroom and you’re the popular girl. He secretly have a crush on you , he’s so in love with you but you didn’t even know his name

one day he was sat next to you in class math and you were struggling with the exercise and Kai noticed it. He gave you a paper and smile shyly at you

"it’s…it’s the answer of the..the problem..I saw you were struggling with it"

did the nerdy guy of your class really gave you the total answer of the problem just like that ?
