My older cousin introduce me to K-drama. Before that, I used to watch any drama on TV. Mostly Cantonese, Chinese, Hindi, Japanese, and Taiwanese. My first K-drama was probably Hotelier. I watch it five times or more.
I feel you, one day I found KinnPorsche and woah, a new world open but it's an explicit one, R18+ maybe. And I exchanged my knowledge with one of my colleague. She's a Thailand BL expert. She love Earth Pirapat of A Tale of Thousand Star fame the most. I found random handsome actors on youtube shorts like 'my favorite BL actors' or 'BL tops' or similar and she can named all the actors I didn't know. But nowadays she asked me new titles. Am I becoming an expert? ^^,
While my cousin is Chinese costume drama expert. She offers me The Untamed long before I watch KinnPorsche because she remembers I like Xiao Zhan (on Oh! My Emperor), The drama is awesome but it's bromance, and the novel is even more awesome. So if you like BL novels; Cyan Wings, Mo Xiang Tong Xiu, and Priest are among the best BL/bromance novelists out there imo.
