The story in the series trailer initially was what interested me in Oxygen but once I started watching I was struck by the talent of the actors. The different character stories are weaved together expertly. Although I found them all interesting, Gui and Solo's tremendous chemistry on screen quickly made them my favorite characters in the series. I found Gui's sober advice and caretaking of Solo to be striking as he is the smaller of the two men, taking on a role that usually isn't found in the smaller of a BL couple. Solo is tall, a talented musician and singer, and the younger of the two men. He comes across as vulnerable, solemn and quiet. I found the mix of their character personalities to be very intriguing and different from what is usually portrayed in this genre. The music performed in the series is wonderful. I have a hard time getting it out of my head after watching. It is without a doubt my favorite series of 2020 so far and I hope it comes back for a second season.
