it's my personal headcanon of mine that he spent his hot divorcee winter discovering the wonderful world of masturbation 🤭 but that probably didn't extend to prostate orgasms. nah, that probably wouldn't happen until he approaches dong sik one day, all clinical and proper, like, "lee dong sik-ssi, I read a... medical article..." and dong sik is just so happy to help him out with this particular "medical experiment"
1000% agree!! He comes back from Busan serving cunt, flirting with Dong-sik and telling his father that he's never had a fling before but he's going to try it out. He was out there .... discovering himself a little bit 😏 It's also my opinion that Joo-won's approach to sex is to read up on it and practice a little himself beforehand. This is the guy who meticulously reads every case file on a 20 year old murder case and stalks the object of his affection obsession before approaching. He knows how to do his research!!
I'm screaming my head off imagining this exchange about the medical article... Joo-won presenting this info as if it's something brand new and unheard of... Dong-sik's shit eating grin when he realizes he's about to blow this boy's mind 😂
