I somewhat agree lol but I guess I was still rooting for switching in Flashlight Yujin's whoreness wasn't there for long in the story, we only see him sleep with one other person then he got with Aaron pretty quickly. Meanwhile across two different series we've had to see Uno flirt with countless people including his own university students and his friend/coworker who very clearly doesn't want him, and we've also seen him sleep with five different people who aren't his actual love interest. Like damn someone really needs to take him down a peg
"There should more switch couples" yes but not this one. Seo-in and Yeongwoon from Backlight should switch. Aaron and Hunter from Flashlight should switch. Woowon and SeoAn from Pizza Delivery Man should switch.
Meanwhile Uno should never top again in his life.
