As much as i like Khao and First i dont think their chemistry was particularly good here... it felt a bit awkward, maybe it was just the characters bc I think First suits rebellious roles more like in Not Me. I think he had better chemistry with Gawin and he's honestly cuter as bottom imo lol... but whatever, they might work better as a couple in Only Friends.
I think it's weird how he suddenly starts talking with no problem in ep 3, like i felt like there could have been a build up or something, or he should have been more awkward when he first started talking... like he went from super awkward in ep 2 to doing just fine in ep 3... like.. and im sad they dropped the stuttering
