Meet Marvin Achi, Houston's star in "The Circle"

Catch up quick: Contestants compete in a virtual popularity contest, vying to become the coolest of them all. Some contestants catfish as other people, but Achi has come into the game as himself (although he's posing as a fitness trainer instead of a chemical engineer).

💪 Here are five things to know about Achi:

• He is 28, was born in a small village in Nigeria, and loves to show off his abs.
• He has degrees in chemical engineering, chemistry and mathematics, MySA reports.
• He's a chemical engineer for Zindu Nutrition.
• He was originally cast on Season 24 of "Big Brother," but was recast before filming started.
• Without any spoilers, he's involved in some of this season's biggest drama.

What we're watching: The next four episodes of Season 5 drop today on Netflix.
