- “Seriously, K-dramas these days are just getting weirder and weirder.”
- “I totally thought it was a flashback scene, but now they’re saying they meet again and get involved??;;”
- “Lee Jung Jae was confirmed for the role first, so why do they keep casting much younger actresses as his co-stars? I just don’t get what the production team is thinking.”
- “Are they kidding? They keep pairing him with younger actresses. The age gap is way too big—15 years, and she’s supposed to be his first love?”
- “For a second, I thought it was Oh Yeon Soo and finally, the age would make sense…”
