In real life I can't stand people that act like Dean and Moth, I despise them so much. I know they're fictional characters but because of this while watching the episodes I continued to get either annoyed or bored. Same thing for Ten.
Which parts are you considering AI, I’m just curious… granted, I’m only most of the way through episode…
All the driving scenes, the first 30 seconds, all the sceneries and places you see from outside and the past scenes of them as child/teenager and their younger selves are AI.
At the beginning I wasn't really fond of this series but episode after episode both couples really won me over. I think both have really great chemistry and TeshowPing surprised me with how good their kisses are.
The sister was annoying and ungrateful from the first episode. She and her friend got hurt because she was arrogant and wanted to play detective Conan with a literal criminal but she's acting like it's her brother fault. The identity of the killer and of the corrupted officer were obvious but it's still a very good series.
Krit and Mochi are the most annoying characters ever, they are so self centered, they really think Rin is always thinking about them THE WORLD DOESN'T REVOLVE AROUND Y'ALL. I always wanted AunStamp as a proper couple in a bl and they gave me this😭
Amazing show, the plot was interesting and the acting was very good. I never got bored, there were some non-obvious plot twists. GMMTV should let their actresses play more characters like these insted of limiting them to side characters.
FNC ent. is everywhere in this drama. O Sole Mio by SF9 in the first ep, the two main actors are both from FNC (and Yu Jun hasn't debuted yet). Interesting...
