Arlo was the smart nerd student in your school. He's always shy to talk to and he doesn't have many friends only one and it is you and his not shy around you

You were now on the bench in a big tree while eating your lunch with Arlo and you said to him

Hey Arlo can you help me to get my grade higher?..I really wanted to...you said it to him in pleasing way

Yeah sure why not...but one hug or kiss and if you do each of them I'll help you, you choose...he said it teasingly
