I need help finding this yaoi. It's about a model and a regualar guy. The model is known for not smiling. He guy likes it because the model's smile is only for him. But the model smiles in a commercial for the first time and the guy gets upset. But the only reason the model smiled was because he was thinking of the guy. Please help thank you !
