I don't know if the landlord used to correct his teeth because they had tiger teeth or some prominent teeth. At that time, the teeth opened his lips, and his lips adapted to the long-term tooth state of more than ten or twenty years. When the teeth suddenly retract to the normal position, the adduction of the lips is not as loose as the adduction of the teeth and looks too thick. However, changing the muscles around his lips takes time. Can you change it to what you want? It also varies from person to person, so the landlord doesn't have to care too much about the thickness of his lips. As long as the teeth are beautiful, thick lips are also a symbol of sexy fullness nowadays. After oiling the retainer, if you really care about your lips, it's not bad to do a micro-plastic surgery on your lips. Anyway, come on.
