First, make sure you have a stable internet connection. Then, download the Bl Kakaopage app or visit their website. Log in or create an account if needed. Once inside, navigate to the manhwa section and select the one you want to read. Some may require a subscription or payment to access.
There are several dedicated BL manga websites. For example, Mangago and Kissmanga have a decent selection. But be careful as some of these sites might not be legal or safe.
Some libraries might have digital collections of BL manhwa. Also, you could check out social media groups or forums dedicated to BL manga, where people often share recommendations and links to where you can read them. Just be cautious and follow the rules and regulations of the platforms.
