I’d have to say that though this is seen as one genre, there are significant differences between the different shows and you may like some and dislike others.
From the examples I gave here, The Novelist and Mood Indigo (otherwise known as The Pornographer season 1 and 2) are completely different from the others I mentioned. The others are totally innocent love stories that just happen to be about men, whereas The Novelist and Mood Indigo are less innocent and rated NC-17 on Viki.
Yet, despite all that, I’d also have to argue that The Novelist and Mood Indigo are masterpieces in their own kind, with psychological depth, humor, tragedy and a beautiful soundtrack.
But if you’d rather try a more innocent one, I’d recommend Because Of You 2020, which also has a nice soundtrack:
And even though it’s a Taiwanese show, there was a Korean guy in it, so it has a Korean song as well:
Whether the actors look good, is a matter of taste I would say, haha. Same in other dramas.
It comes from the Japanese genre Yaoi: https://de.wikipedia.org/wiki/Yaoi
Lol, I actually did have a gay friend in my youth. Though for most of that time he was not aware of that yet and neither was I.
I’d have to say though that a straight man can just as well be a good friend. Despite what some say, lol.
