Earth is cheated on by his boyfriend sam with his best friend stud
I will say if you liked My Fuxxxxx Romance, you will be sucked into Friend Zone and invested. Friend Zone has the love triangles, but it is WAY MORE TWISTED! Just a warning that there's a lot of cheating and explicit content. It also has BL relationships if you were interested in that too. I will say, if you watch the first season, you need to watch the second season.
Both dramas center around a group of young adult friends in a professional setting, both include straight and gay couples, and both explore similar themes in terms of relationship struggles, including infidelity (Friend Zone is more diverse in the challenges it explores, but both have similar vibes).
