Season 1 of Only Friends premiered on August 12, 2023.

Mew, Ray, Boston and Namchueam—a group of business students running a hostel together—blur the lines between friendship and romance.

Mew has been focusing on his studies, setting aside no time for sex and relationships. To help them with their business's design, Boston introduces the group to Top. Boston didn't anticipate Top's interest in Mew and he isn't happy with the turn of events. Economics student Sand wants an exclusive relationship with Ray, but Ray has feelings for Mew and he's not interested in settling. IT guy Nick finds a sex tape in Boston's phone and ends up in a friends-with-benefits relationship with him. However, Nick wants something more.
