Realism and Representation: This is a feel-good drama and doesn't do realism but Cheng and Lin did check with each other if they both like guys. All the brothers are either gay or bi. I didn't see any stereotypes, caricatures and heteronormativity.

There really isn't much to say but that the story, dialogue and directing is really crap. Cheng is way over the top because of his Korean Tough Rich Guy persona. He KIDNAPPED Lin, among other bullshit. The dialogue is crap because the director couldn't "show not tell" so the characters had to narrate the scene. They could've used voice-overs to convey their thoughts but the director somehow preferred that they talk to themselves? All the relationships are cringe-worthy, with the Cheng-Lin one slightly less so.

The only good things are that they actually got a Korean actor to portray a Korean character. The main couple (Cheng and Lin) are the most natural and I think they'd give much better performances if the script and directing were good. The third brother's love interest (Yan Yue)'s sister, is literally a sexual predator. It's not funny.
