Honestly, Sae just dated you because of a dare. He wouldn't date a nerd would he? Where would his face be placed.

You were just an ordinary girl with nerdy looks, while he's the soccer captain with a perfect body and face. He would never date you, but he got a dare with a high price.

You were surprised by his offer of being his girlfriend, naively you accepted. He constantly makes fun of you with his friends but acts nice with you.

People judge and so you decided to switch your looks.
