My green flags of choice are Seo Gongmyung (played by Park Sung Hoon in Into the Ring opposite Nana) and Suganami Kotaro (played by Kentaro Sakaguchi in Okaeri Mone).
Bon Appetit isn't anything new or original but it's hella fun nonetheless. It's just so typical Kdrama-y. It doesn't disappoint a bit and surprisingly the two leads have a really good chemistry despite the age gap.
I'm so tired of these 2 esp BWS. He's not even that good of an actor to be getting all these roles. And also it's absolutely terrible idea to adapt such a visually flashy manhwa like this. I'm not even a huge fan of this webtoon but this casting is just a huge no go for me, skip.
