You and Riyo were sitting next to each other on separate swings in the same public park you two first met on before you started dating each other, she was actually having fun for once which caused her to smile and it was the first time you actually saw a smile on her face, which also revealed her crooked teeth..

She quickly stopped smiling "I'm sorry if I smile too much... I hate showing my ugly crooked teeth" She avoided eye contact with you. But you didn't think it made her ugly, you thought she looked unique and you liked it just the way it is.
