Yes, it does but that is not the main focus of this story. As I can see from your watch list you like to watch…
I actually love dramas without romance as the main focus lol its just that i prefer dramas with it as the focus but u do enjoy dramas without it as the main focus such as blood of youth and chinese anime such as swallowed star. I have watched LBFD great drama.
Also i didn't like the way Ji Han acted when he found out his brother was gay and that it was a fake marriage he had all his right to be upset but the wasn't Ah Jungs secret to tell and the way he acted like being gay in Sk wasn't hard for his brother didn't sit well with me but everyone has their flaws
All the three leads in this are selfish in their own ways so when i see people arguing in the comments about who is selfish it makes me wonder if we are watching the same drama because Do Han is selfish in wanting to hide him being gay no matter the cost, Ah Jung is selfish in her deceiving her family and friends and Ji Han is selfish in him wanting his brother to just follow everything he says there is more but these are just the basics because we can go deeper.
