20 Dating is a website for finding a partner with a huge age gap from you— at least 20 years, to be more precise. The site might be trying to remove the stigma of this kind of dating. It is quite different from sugar-sugar daddy/mommy relationship because it involves the intentions of being in love or getting married.
The site is one of the dating websites of DMCube which also produced PureScarlet, Bald, and DinkyOne. Mostly of 20's sister sites belong to uncommon niches.
