Could it be the Taiwanese show Plus & Minus (2022)? They are friends, live together, one is in love with the other but keeps it a secret, they spend time out at a bar and the oblivious one always flirts with girls...
I would need to get the feel of the series... There is another Taiwanese drama but the BL is a side couple. They are not friends at first but they start getting along; one guy is a womanizer and even a bit prejudiced against gay people, and the other is a guy gay and ends up falling for the womanizer. They pretend to be together at first for certain reasons, but end up a couple, it's called Love Is Science?
I would like to get the feel of the project because there are a few that would fit the description.
Can you describe the characters?
There is a Thai show as well called Big Dragon 2022, they were friends as children, did not see each other for some time, because a type of rivals, one is a womanizer the other is in love with him... they had a scene where the womanizer was not ready for a relationship or to be openly gay and pushed the other away...
